Review on TECHMAX H4 LED Bulb: Small Design 10000LM 60W 6500K Xenon White ZES Chip - Brilliant 9003 Halogen Replacement Kit (Pack of 2) by Jeff Prabhu

The quick start guide for them said that if the car has fog lights they might interfere with the radio and the low beams might not work. Both have come true in my car. The radio interference was negligible, so I ignored it. I contacted the seller about the low beam and he immediately sent a resistor for each headlight which solves the low beam/fog light problem. The only downside is that the resistors must be carefully mounted on a metal surface in the engine compartment and not near plastic, rubber or wiring as they get very hot. (It is in order.)
