Back in June I bought 10 1156 Super White LEDs
They were bought to replace:
2x Reverse Lights
2x Turn Signals
1x CHMSL (3rd Brake light, etc...)
They never worked in the CHMSL here's why:
Daewoo reverse the polarity to the bulb.
Snipped the wires and reversed them.
Showing it was infact factory this way.
SUCCESS! Now any 1156 LED Bulb will work!
DONE! I added some wires from a dead computer PSU and then wrapped the whole thing in electrical tape.
