Question: if I place a diode (i.e., 1N4004) coming off the brake light wire, & another diode (same type) coming off the running light wire then connected to a resistor (i.e., 68Ω), then connect both these to stock 12V LED running lights, will they brighten when the brake is activated?
Background: I'm working on my motorcycle. I want to convert 12V 'plug & play' LED truck clearance reflectors to run/brake lights. I have added the LEDs to the saddlebags on my motorcycle.
I'm not positive about the resistor size since I have no data on the lights except they're 12V but I can play w/ the resistance to get what I need.
I have searched the net extensively, including this site. The 3 threads that come up on this site really only gave one solution: Sgt Wookies, but that is not doable short term because a) I have no shottky diodes; b) I have no pnp transistors.
