you need to check your bulb physiccaly, H4, H1, 9006, 9005 or what ever model.
you must add relay for installing HID, it's common practice, not to burn your stock wiring if too much load for the HID.
Thanks for the info dude. Whats the pricing like in KL nowadays? Over here its like $300 AUD for a decent good quality kit (RM 888).
Last time I was in KL, prices were like RM1000++ for all in with relays.
Are the prices in KL much better now? If not, then I think I'll just get it here, to save my uncle the trouble.
