The lower, the better. Standard is 55W/60W low/high. You can go with 80/100 at the max but keep them aimed properly. You already know the size (h4/9003) and number (2) of bulbs. Check what gauge rating your standard wires are set to, then get higher ones and reroute them properly.

Note however that no matter how much wattage you increase, cleaning the lenses is probably the easiest and best way to get as much light on the road. Also note that if you have plastic headlamp housings, you can't go too far higher than stock, because you will melt the reflectors if they're plastic, and/or the headlamp lenses if they're also plastic. Don't forget the wiring sockets, the originals are probably plastic too.

Another option is just by buying good H4 bulb eg. Osram Silverstar 50%, Philips VisionPlus 50% and the better Philips Xtreme power 80%. These are in stock wattage so u don't have to upgrade you wires,socket,relay. The % denotes the light improvement over ordinary halogen bulb.Dati un mga 50% nasa +-1000Php/pair.Baka mas mura na ngayon.

For me, this is the safest route to take (especially if still under warranty). No need to change anything except for the bulbs them selves.

Electrical loading will not change. Stock wattage (same power consumption) but brighter.

try cleaning first your headlight housing then buy a new set of h4 bulbs. bulbs diminishes its brightness as it grows old. I usually replace bulbs yearly

THANKS SIR MBEIGE. IM GOING TO CHECK THE HEADLAMP HOUSINGS IF ITS IN PLASTIC TO AVOID MELTING THEM..

*DRIV3R: I'LL CONSIDER YOUR OPTION. THE PRICE THAT IM GOING TO SPEND IS NOT FAR FROM THE PRICE OF PHILIPS OR OSRAM BULB THAT YOU SUGGESTED. THANKS

*MELEDSON: YES I THINK DRIV3R'S SUGGESTION IS THE SAFEST AND EASIEST THING TO DO. THANKS.

*BADSEKKTOR: MY STOCK H4 BULB AND HOUSING IS STILL CRYSTALLY CLEAR. I BOUGHT MY 2ND HAND EK SEDAN WITH A PAIR OF NEW HEADLAMP. I JUST WANT TO IMPROVE ITS VISIBILITY THATS WHY IM PLANNING TO GO ON A HIGHER WATTAGE. THANKS

To give you more options you can choose between these leading stock halogens.
I have an osram silverstar and so contented with it's output, you can compare it with ordinary h4 in terms of light throw but I’m pretty much interested to this new osram night breaker –the couterpart of Philips extreme power. Hope magkaroon na dito nito.
