Modded Chinese 50″ LED Light Bar

A very good friend of mine came to me with an idea. He wanted a 50″ LED light bar for his Jeep, but he wanted it 100% UNIQUE!!!

Challenge accepted!

He was used to running diesel trucks with 3 amber marker lights above the cab. And that’s what he wanted this light bar to do.

I took apart the Chinese 50″ light bar, and came up with a design for a “add-on piggy-back” board. This board would have the new amber LEDs and the drivers for them. The design was such that I needed to remove a few of the OEM LEDs to make room for my new board. It was also designed so that the new amber LEDs would line up with the OEM lens. Here is the gang board from a board house I use. There are 8 boards on this one PCB.

Bench test of the board design with the light bar optics. I used 5050 amber LEDs.

This is one of the 3 boards installed into the light bar. The little yellow things are the OEM LEDs. I took 2 of them out in this section. I just still 12VDC from the + rail.

This is all three add-on boards installed.

Another view.

This is how it looks installed on the jeep, all sealed up (MUCH better then the OEM Chinese had done)

He LOVED IT!!
