Here are some samples. These are pretty much how they will be. I need to order some more LEDs to complete this trial set. I only had enough to do 1 side of the car. The 914 taillights are on the very left and for comparison I turned on the brake lights on my Integra. the 914 taillights are at the very front of the Integra.

I actually tried the FLAPS turn signal flasher, for some reason I couldn't get it to work right. I built a circuit but it cost a bit more than $10... The problem is that in the stock setup, when you engage the flasher, the resistance of the bulbs results in heating of a bimetal strip inside the flasher. So the flasher and bulbs become a single oscillating circuit when the turn signal switch is engaged. My solution was to build a circuit that is constantly "flashing." I used a 555 timer IC and a potentiometer for flash rate control. The switching device was a P-channel FET. These are required because you are switching the +12, not the ground. P-channel power FETs are a bit hard to come by. They are out there, but not too common. A relay would work, but because the circuit is always flashing, the relay would eventually wear out not to mention make an annoying noise. -Tony |
