I own Honda City IDtec. I always have low confidence driving at nights and was looking at head lamps upgrade. I feel factory headlamps have good throw but intensity is not that great. I spent couple of days understanding about headlamps by reading various threads. Prices mentioned here are just rough prices obtained from web. I didn't go to any shop.
1) Do not make make changes. Costs zero
2) Increase to better lamps with same 60/55 Wattage. Costs around 2k for both the High and low Bulbs. Using this will not have any legal and warranty issues. As present bulbs are also Philips, I feel there won't be much change.
3) Use 100/90 wattage bulbs with relay. Costs around Rs 2K-2.5K. Has some disadvantage of heating and some cut needs to be done to head light assembly. May cause issues like frequent fuse blown.
4) Use HID without projector. Costs around 10K. Many say this will blind in coming vehicle.
5) HID with Projector. Costs 25K -30k. Tough to convince dad and wife :)
Please let me know your experience with different options? If I get good reviews on Option 2, will try that out.
