    Hi Liz,

    If you already upgraded your headlight wirings and installed relays, you should be able to use bulbs with the wattages you indicated.

    As for H4, it's a type of bulb. Not all lighting systems use the same type of bulb.

    Hope that helps.

    Before using hi-wattage head light bulbs. Hi wattage means na higher than stock. We have to upgrade the electricals first. Sa mga gumagamit ng H4 na head light bulb, normally mula relay to wirings hanggang headlight mismo ay pinapalitan.

    Now this upgraded wirings also have a maximum capacity (in watts).

    Ang H4 kasi has separate wires for the hi and for the low. If paraho lang ang size ng wires, kung ano ang max na watts sa hi ay puwede rin sa low. Normally kasi mababa ang wattage ng bulb sa low.
