Custom LED Tail Lights

at 5:22 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


Dave from Plastibots had some fun with the brake lights of his Nissan Juke. He added some red LED lighting strips to the car and made a custom circuit to drive them. He is getting power from the parking lights and taking in a signal from the brake lights. When only the parking lights are on the lighting strip is PWM controlled to a level of 75%, when the brake is applied the lights are turned on with full power. The control is done in a smooth fashion. I like this since lots of vehicle lighting these days turns on and off very sharply since most of the lighting is LED. I miss the days of incandescent bulbs which had an inherent brightening and dimming delay.


“I wanted to also monitor and react to braking to enhance the effect. I decided to go with an ATTiny85 using the Arduino core. It only needed 1 input from the 12V brake power and 1 PWM output to control a MOSFET which in turn powered the LED light strip @ 12V. I built one controller per tail light.”
