i've been offered WURTH H4 bulbs * 700 pesos each.
i haven't heard of this brand yet. has anyone ever tried this? is it worth the 700 bucks? kasi same wattage lang eh. i'm now using Philips premium H4 bulbs which are good enough for normal night and rain driving.
Despite claims of some superwhites manufacturers, brightness is dictated by true watts rating. Save your money and get quality halogens with ratings that meet your car manufacturer's recommendations. Playing with color temp only creates the illusion of brightness.
If you want to go brighter, install relays for your hi and lo circuits, use thick gauge power and ground wires. Then use 100w bright, 100w/90 hi/lo halogens. Much brighter, perhaps cheaper.
