I'll do a little better job but that was easy and super functional.

I cheated when I did mine. I took the lights off a truck in a scrap yard measured the spacing between and front to back Then took the front edge of the headliner off and used the arc from that as the tmplate fo the top to mark and drill my holes. Then I strun two wires across the inside edge and dasiy chained the lights togther on the single wire. one wire ground and one hot. Then bought the 194 amber 4 led packs of 2 bulbs from autozone for $10 each and plugged em in and voila.

They sell packs of two LED bulbs for $10 per package each bulb contains 4 amber LED's. They are direct replacements for the stock 194 (or I beleive its a 194 bulb). you simply plug them in. They dont require anything to drive them. I use LED's on my tail lights too 3157 replacements in red LED's they are like $15 a set and have like 12 LED's and they work fine as long as you use heavy duty electronic flashers as they dont create enough load to cause thermals to flash. they barely create enough load for electronic flashers, if you convert the front amber flasher there too youll need to introduce load balancers to keep them flashing.

Standard factory flashers are thermal, meaning that as the current flows through them they get hot, after the reach a certain temp the contacts break/ open cool then close, thus causing the lights to flash. Heavy duty electronic are designed for heavy towing, and or additional lighting in which there are more flashing lights ie. turnsignals, hazard lights. They are simply an electronic switch that opens and closes the contacts by a timer and requires very little load to drive it. Thermals when used with LED's often dont get hot enough to open the contacts as the draw from the LED's is so small, thus no blink or with too many lights they will blink so fast they appear to stay on. Electronics require less load to operate so they will work with minimal load like the tailights only as I stated, and will not be effected by excess load. To control this problem usually the introduction of load balancers is used. Load balancers dont use any current but have a resistor in them to cause a bottleneck effect to add a load to the flasher units. By the way there are 2 flasher units on our trucks, the first in on the front side of the fuse panel, and the one that controls the 4ways/ hazards is on the back side of the fuse panel.

i added a ulta bright 5mm led to each clearence light with a seperate line for each one so they could be controlled seperatly. a PIC micro controller does all the work. my cousin did the programming. they can do whatever you imagine. it only takes him 5 min to change the program. its triggered by the horn on the keyless entry lock.

Oversize,
Would you have a part number for the flasher you're talking about?
