Hi,
I built an on board lighting system in a WAW, based on these RGB LEDs from DX, but I'm running into a few problems I can't solve. My knowledge of electronics is basic.
Battery used was a 8.4V Sigma iion battery. The rear light and brake light (with reed contact) were respectively regulated from a 350mA and a 500mA driver to the red cathode. The turn signals got 500mA through a digital relay to the red cathode as well. It worked well for a while: these large surface LEDs are discrete and aerodynamic but very visible when lit.
But alas: It all breaks down after a while.
1)Why? Did I do something wrong with the regulation? Are these LEDs very vulnerable to road vibration/shocks? Is it the humidity?
2)How can I improve the system?
3)Is it possible to use the blue component as a running light and have the red component blinking on top of that at the same time?
Thanks.
