[michael bucklew]

converted front turn signal light bulbs to LED. worked....installed LEDs in rear --brake and turn signal. nothing works including front signal bulbs...do I need to do something to the electrical system to get the LED bulbs to work..do they draw more current??? do I need a heavy duty flasher unit?? 2. fan is on all the time with ignition on. even in the off position.

Absolutely, it comes with instructions.

By the way, I’ve seen them sell as low as $10.
