For four-lamp trucks on overnight routes, start with LOYO Storm 4×6 and build a matched order for each beam position. Choose Grote’s heated 4×6 lamps when snow covers the lenses. LOYO Ping Pong 5×7 suits compatible service vans making frequent city turns when your plan needs DRL and turn-signal functions. Truck-Lite’s projector range is the pick to test for stop-and-go delivery after dark. For compatible 7-inch round vehicles with different voltage needs, ask LOYO for the correct King Kong version for each group.
Start with the old lamp code and the number of lights on each vehicle. Then use route conditions, required lighting functions, and voltage to narrow the shortlist. The table shows where each pick earns its place and what you need to confirm before buying.
Five Headlight Picks for Common Fleet Problems
| Your main problem | Best pick | What you gain and need to check |
|---|---|---|
| Overnight-route four-lamp trucks need a repeatable replacement set | LOYO Storm 4×6 | Super bright light output with Factory-direct wholesale quote for matched positions; ask about connectors and labeling for your order. |
| Snow blocks the face of a 4×6 headlamp | Grote heated 4×6: 64J61-5 / 64J71-5 | Heated lenses address buildup; confirm low/high positions and 12–30V supply. |
| Service vans make frequent city turns and need added lighting functions | LOYO Ping Pong 5×7 | DRL and turn signal in one listed lamp; ask for factory-direct wholesale pricing and a wiring plan. |
| Drivers make frequent turns and stops on city routes | Truck-Lite Next Generation LED Projector | More foreground coverage by design; match the specific lamp and vehicle. |
| Mixed-voltage vehicle groups share a 7-inch round format | LOYO King Kong 7-inch | Request factory-direct pricing by approved voltage and beam SKU; discuss branding for larger orders. |

Best for Four-Lamp Trucks on Overnight Routes: LOYO Storm 4×6
On an overnight truck route, a failed headlamp can leave your maintenance team sorting through four positions before the next shift. Start with LOYO Storm 4×6 if your trucks use a compatible four-lamp system. LOYO’s 4×6 LED headlight range lists candidates for H4651, H4652, H4656 and H4666 systems; the exact inner and outer units still need to be matched to your truck.
Send the old lamp codes, a photo of each position and connector details to LOYO. As the factory supplier, we can quote the approved parts at wholesale prices and discuss order labeling, packaging or connector changes for your fleet. Your team gets a position-by-position parts list to use at the pilot install and for later replacements, with fewer chances to pull an inner lamp for an outer position. Custom changes need a fitment and feasibility review before we quote them.
Choose Storm if: you replace 4×6 lamps across a group of four-lamp trucks and want one repeatable buying plan for the next night shift. Confirm the voltage, beam function and road-use documents for each selected SKU on a pilot truck before you stock a full set.
Ask LOYO for: an exact four-position SKU list, the corresponding beam function, voltage range, connector details, product-specific road-use documentation, a sample set for one truck, and a factory-direct wholesale quote. Tell us if you need custom labeling or packaging.
Best for Snow Routes Where Headlights Ice Over: Grote Heated 4×6
If your drivers stop to wipe snow from LED headlamps, you have a lens problem to solve. Grote’s heated 4×6 low-beam lamp 64J61-5 and high-beam lamp 64J71-5 are built for that route. Grote lists automatic lens heating and 12–30V operation. You can specify the correct low- and high-beam parts for a compatible truck rather than asking drivers to rely on frequent manual cleaning.
The expected result is a lens that sheds snow and ice buildup during winter use. Check the old lamp codes, each beam position and the vehicle’s supply. Fit and heat operation deserve a pilot test on a truck that actually runs the snowy route. A two-lamp sample tells you little about the other two positions on a four-lamp vehicle.
Choose Grote if: your compatible 4×6 trucks regularly collect snow on the headlamp face. For dry routes, compare standard 4×6 sets first; the heated function adds value where lens buildup is a recurring maintenance task.
Best for Service Vans Making Frequent City Turns: LOYO Ping Pong 5×7
Think of a service van moving between calls across town: daytime traffic, repeated turns and a vehicle that may need extra lighting functions. For a compatible 5×7 headlamp setup, the LOYO Ping Pong 5×7 lists high and low beams, a white DRL and an amber turn signal in one assembly. Its product page includes selected Chevrolet Express and GMC Savana applications; confirm your exact van before you order.
Model LY-DYSF7-02 is listed for 9–32V input and IP67 protection. If your upfit calls for the added functions, send LOYO the old lamp code and your wiring plan. You can get a factory-direct wholesale quote for the approved van group and discuss custom connectors, branded packaging or another project-specific change. After a sample install, your technicians can work from the same documented lamp and wiring plan each time that van group returns for service.
Choose Ping Pong if: your 5×7 service vans need daytime running lights and a turn-signal function. Check the retaining ring and connector, wire and test every function, then aim the low beams on a pilot van. We can review custom requests against the actual vehicle and order quantity before offering a production quote.
Ask LOYO for: fitment confirmation against a vehicle photo and old part number, the wiring diagram, product-specific compliance documents for your destination market, a sample pair, and factory-direct wholesale pricing. Include your packaging or connector request if you want a custom version.
Best for Stop-and-Go Delivery After Dark: Truck-Lite LED Projector
A delivery driver makes far more close-range turns and stops than a truck running straight through the night. Side streets, loading bays and work zones put the area just ahead of the vehicle in constant use. Truck-Lite designed its Next Generation LED Projector Headlights with a wider beam spread and greater foreground coverage for final-mile delivery, utility, construction, municipal and waste vehicles.
That design makes Truck-Lite a sensible choice when your drivers need useful light in busy, close-range work. The announced range includes 4×6, 5×7 and 7-inch round lamps. Pick the format that matches the installed headlamp, then request the exact part number and test its low beam on the route. The announcement does not provide a vehicle-by-vehicle fitment list.
Choose Truck-Lite if: your compatible vehicles spend evenings on stop-and-go urban routes. Ask the supplier for voltage, connector, beam direction and road-use documents for the version you test; confirm the foreground pattern from inside the vehicle after installation.
Best for Mixed-Voltage Vehicles With 7-Inch Headlights: LOYO King Kong
A mixed vehicle group may have 7-inch round headlamps on both 12V and 24V systems. The mounts can look alike even when the electrical and beam versions need separate orders. With LOYO King Kong, you can ask our factory to quote a standard-voltage group and a suitable wide-voltage group under one procurement plan. The linked LY-KK7-001 is listed for 9–16V; LOYO’s separately published RHD model LY-KK7RHD-001-B is listed for 9–32V DC.
Put the approved SKU and beam direction next to each vehicle group in your parts list. That gives the buyer and the service team a clear choice when a lamp needs replacing. For 24V work, ask which wide-voltage version is supplied for your LHD or RHD market; a 9–32V RHD listing alone does not confirm an LHD version. As a manufacturer, LOYO can provide a factory-direct wholesale quote and review custom branding, packaging or wiring requests for the approved order.
Choose King Kong if: your vehicles have verified 7-inch round mounts and you want an organized replacement plan for different electrical groups. Check the bucket depth, connector, adapter and DRL wiring, then test one vehicle per voltage and beam version. Ask for the exact product-specific road-use documents before a wider rollout.
Ask LOYO for: the exact standard or wide-voltage SKU for each vehicle group, its stated input range, LHD or RHD beam version, connector and adapter, mounting dimensions, DRL wiring plan, the certificate or test record for the supplied SKU, and a factory-direct wholesale quote. Share custom packaging or branding needs with your vehicle list.
When a Vehicle Needs Its Own Headlamp Assembly
A molded, vehicle-specific headlamp usually needs its own assembly. Measure-and-guess ordering wastes shop time, especially when the original lamp carries a unique mounting bracket or electronic control module. Send LOYO the vehicle model and year, old headlamp part number, clear photos, connector view, and required functions. Ask for a compatible product or an OEM/ODM proposal if your project needs a new housing, custom appearance, packaging, or wiring.
For 4×6 snow routes, Grote’s heated pair above offers a documented lens-heating option. For vehicles using another headlamp format, request a heated product designed for that exact system; a 4×6 heated lamp cannot replace a 5×7 or molded housing.
Road-use paperwork belongs to the exact lamp and market. In the United States, NHTSA’s FMVSS No. 108 interpretation explains why an LED replacement bulb and a complete headlamp assembly are different regulatory questions. Request the documents for the precise assembly you will install; do not extend one SKU’s marking to a whole category.
How to Approve a Fleet Order Without Guesswork
- Split the fleet into headlamp groups. List the vehicle model, year, old lamp part number, lamp count, and operating voltage for each group.
- Choose one candidate per group. Send old-lamp, mounting-ring, and connector photos. Ask LOYO to identify the exact SKU and any added wiring or adapters.
- Check the approval documents. Match the documents to the exact product version and the market where the vehicles run.
- Test one vehicle per group. Install, aim, and check high beam, low beam, DRL or turn signals where fitted, then run the vehicle on its normal route.
- Place the repeat order. Agree on SKU identification, spare units, packaging, warranty handling, and delivery schedule before wider rollout.

Fleet Buyer Questions
Can I use the same LED headlight across every vehicle in my fleet?
Only across vehicles confirmed to use the same compatible headlamp system and electrical setup. Group your vehicles by old part number, voltage, mount, and connector. A shared lamp size alone is not enough.
Which LOYO option should I ask about for an older service van?
If it uses a compatible 5×7 headlamp, start with the LOYO Ping Pong model LY-DYSF7-02. Confirm your van’s year, old lamp part number, mounting ring, connector, and wiring before ordering.
Will King Kong work on a commercial truck with 7-inch headlights?
It can be a candidate. The linked LY-KK7-001 is listed for 9–16V input, while LOYO’s wide-voltage RHD version LY-KK7RHD-001-B is listed for 9–32V DC. For a 24V truck, request the correct wide-voltage SKU and beam direction for your market. Confirm the mount, connector, DRL wiring, and road-use documents before ordering.
Are all 4×6 headlamps in a four-lamp truck identical?
No. Identify the original part number and function in each position. Ask for a four-lamp set matched to your truck’s high- and low-beam layout.
What’s the best led headlight for fleet?
Best led headlight for fleet for different conditions. best for night driving is LOYO Storm 4×6. Best for frequent city turns is LOYO Ping Pong 5X7. Best for daily upgrade and mixed voltage is LOYO King Kong 7 inch.
What should I send to get a useful bulk quote?
Send a vehicle list, photos of the old lamps and connectors, the destination market, estimated units per fitment group, and your target delivery schedule. Mention if you need custom branding, packaging, or wiring.
