Upgrade car headlight bulbs
I would like to fit Zorbes H4 12V 60/55W Halogen Bulbs 6000K Xenon in Hyundai Elantra car which has H4 60/55w bulb connector . But below are some dauds and would be pleased if you could kindly help me.
1. Being of the same specs with this particular car, can I used just by replacing the factory fitted bulbs?
2. Do any extra wiring is necessary for the new bulb and should relay be compulsory for the bulbs to work in this car?
Is this a good question?
