Latest project - adding LED's to the Williams EZ Street police car!
I wired the five LED's (two headlights, one flashing light for the siren, and two taillights) in series and the circuit was fine when tested before installation in the vehicle. When I connected the positive lead to the pickup roller and grounded the negative lead (installed them in the vehicle) they ceased to function properly. The strobe light does not flash regularly and the headlights and tail lights flicker. I am running them off of a DC power source for the flashing LED.
Should I have wired them parallel with resistors or do I need a small constant voltage power source in the vehicle? Any help would be appreciated.
I am sure someone will ask me for more information, as I am sure I have left something out of this post !
