Some vehicles electrical system may require a relay harness to cars with very small gauge wiring that cannot supply the initial surge current required to light the bulbs reliably. It may help resolve potential flickering issues or lights not turning on when connected to the HID kit. Symptoms indicating the relay harness is required would be intermittent starting or lights going out after being turned on for several minutes and requiring you to turn the lights off and back on for them to turn back on again. The relay harness basically helps regulate the power and keep the lights on when turned to the on switch.
9 down, 23 to go. Heard a guy at Walmart complaining to his wife that these cars are not properly scaled. Even said the same about m2 cars. I mean sure it might not be perfect but I mean at the end of the day it's a collectible toy. #toeachtheirown#fastandfurious#mattel
