question about headlight bulbs

**the_noise** · February 20th, 2007 08:57 PM

Question lang... Malaki ba difference ng buga and kulay ng ilaw ng all weather 100/90 vs 130/90 na h4 bulbs?

Napundi kasi yung lowbeam nung isa kong headlight kanina, e medyo mahirap maghanap ng 130/90 na pamalit. I was thinking kung halatang iba ang wattage kapag 100/90 lang pinalit ko.

And kung may alam na rin kayong bilihan ng 130/90 na bulb, preferably around QC, paki post na rin.

Thanks po!

Sir try nyo mo sa sm north or sm frvw. Infinity name ng shop. Nakabili na ako duon dati ng 130/100w na bulb. Meron din sila 170/110 n bulb.

Be careful. With wattages that high, you may end up melting your wiring harness.

and more often than not, they dont produce true wattage figures as claimed on the label. parang sales talk lang. just get a good set of all weather bulbs, upgrade your wires and harnesses, then install a relay. you'd notice a big difference in illumination

Three concerns:

1. Melting wiring harness
2. Melting plastic reflectors if your car has those instead of metal reflectors
3. Increased workload for alternator and possible shortened life of alternator and/or battery.

Note: aim them properly so you can prevent glare AND still see optimally (what's the use of increasing wattage if they're pointed in the wrong direction?)....

Thanks for the replies. I've been using Hella 130/90 all weather bulbs for the last few months, wala namang problema. I'm also using a high wattage harness na, with heavy duty fuse. Wala namang problema, napundi lang talaga.

It just doesn't feel right na papalitan ko ng 100/90 kung galing na ko sa 130/90.
