Hello I installed an aftermarket HID kit on my car which normally comes with halogen
bulbs, thing is the lights flicker. Been reading and some suggest using a relay others a resistor. What would be the best way to go about it in an RX8?

 

Which HID kit did you have?

 

If both sides are flickering it can be caused by a few things. More than likely because the car can’t supply enough power to the ballasts on startup. You can check this by connecting the adapter cables on the bulbs to the battery with the bulb and ballast connected. If the kit fires up without any problems you will probably need a wiring harness.

If your car has Daytime Running Lights (DRL) if could be caused by the car quickly turning the lights on and off to give the effect that the halogen bulbs are running at half power. If the flickering is caused by the DRL you can try a wiring harness or have the DRL disabled (NOTE: disabling the DRL may not be legal in all areas, check with local laws before doing so). The flickering can also be caused by the car’s self-check system to see if there is a working halogen bulb connected. This can typically be corrected with the BOW3.

 

Thanks I'll try connecting them directly to the battery see if it helps. My car doesn't have DRL. If that doesn't work I googled some sites where I can order the BOW3.
