## Description

Emergency Vehicle Warning Light, Grille/Deck/Dash Light, Mini Light Bar, PA System Siren, Off-Road Light Bar & Equipment at high quality and low price. _Make your life fair again_ All LED headlights upgrades could be plug and play simple But of course, if so, life is fair and as you know, life is not fair In some cases, the position of the OEM pin does not match with the new LED headlight plug, so the wire will need to be relocated. Not so bad. But then your vehicle uses a completely different type of headlight circuit, and the wire may not be rearranged at all, and standard LED headlights will not work with your OEM harness. What about that? You can perform all research to find a way to properly use the relay and fuse to convert your OEM harness, buy all parts and spend hours on wiring. Or you can save money, time and headache by purchasing our conversion harness. _ Designed to last_ When designing a conversion harness, we made sure it is a comfortable fit for our vehicles. That's why two sturdy Bosch style relays, high temperature ceramic sockets, heat-resistant polycarbonate wire looms, and a 30 amp fuse to protect your lights and vehicles. _ Exceeds Warranty_How often does this part warranty?

## Questions & Answers

**Q: will these still trigger the high beam indicator?**
A: This will vary from vehicle to vehicle.  Some vehicles' dash light indicator lights up only when a good amount of power is being drawn through the original high beam circuit.  Since this wiring harness omits the factory circuit, and only uses 150mA to trigger the relay through the factory circuits, it may cause the vehicle to fail on noticing the high beams being on.  Hope this helps.

**Q: Would this harness work for a 1985 Chevy c10 ?**
A: Yes as long as it’s a square headlight truck

**Q: got harness for led headlight for 1992 toyota corolla dx, hi beam indicator doesn't come on now, what loading resistor do I need to get for that?**
A: Wish I could help. I’m having troubles with the led headlight for my 1987 Suzuki Samurai. Only the running light continues to work.

**Q: Do you make this for a 2006 dodge 2500?**
A: Yes it’s good for any application
