A ballast resistor must be installed between wires going to the bulb socket. I created my Installation instruction as well.Īvailable for ordering About ballast resistorsįor North American cars ballast resistors are not necessary if front bulbs are 27W.įor cars, where the front bulbs are 21W, like in Europe and Asia, 24 Ohm 10W ballast resistors are necessary to avoid hyper flashing issues.
Using Mazda instruction, it took about 30 minutes from start to finish. I think the number of LEDs can be reduced to 24. For this video I dropped the power twice, otherwise, it is hurting my eyes. Unfortunately, the lens and mirror inside this unit reduce the sequential effect. The next video shows PCB installed inside the light unit. My PCB has white masking, to make it less noticeable inside the unit, and a 3D printed T20 plug and a support clip. The original bulb rated 500 lumens The new LED light will produce about 720 lumens (about 20 lumens per LED) when all 36 lights light up. I chose high power OSRAM yellow LEDs because I had experience with this brand before and they seem very reliable. The inserts alone increase the brightness of the taillamps by 200. Scotts goal was to provide the classic Mustang with sequential turn signals like the T-birds and Shelbys of the 60s. I found NXP 12 stage shift register to control LEDs, and PIC microprocessor to control the shift register. Another new and unique product from Scott Drake. This fits perfectly inside the available space. I did a quick 3D design and printed a plastic mockup, to verify the shape of future bulb replacement with 36 (3×12) LEDs. After taking a closer look at the light unit design, I found that I can fit there a 4″ long LED light to produce a similar effect. I decided to design a simple bulb replacement instead.
#Sequential lights install
He has actually cut the light unit with an ultrasonic cutter, to install LEDs there, which is quite a complicated process. This project was inspired by the work of Kenji Ganakuto on YouTube.
