Either:
1. Upgrade to a better H4 bulb (i.e. Philips Xtreme Vision, Osram Nightbreakers, etc.)
2. Go for a projector retrofit.

If the bulb you put in is loosely mounted, it might cause an electrical short later on or have a shorter life. H4 housings also don't work too well with HID bulbs from what i know. MAs panget yung buga and nakakasilaw.

What car is that for BTW?
