H4 Bulbs - 60/55W Vs. 100/80W? - NJFBOA - Home of New Jersey's Camaros and Firebirds

Hey all,
I recently upgraded the headlights on my Jeep to Rampage conversion housings that take an H4 bulb, and I also upgraded the wiring harness with heavier gauge wire and relays to run the headlights so I could take advantage of higher wattage bulbs. Now, does anyone think I'd get hassled if I ran the 100/80W bulbs over the standard 60/55W bulbs? I only ask because I'm not all that crazy about the bulbs that came with them, so I figure if I have to buy new ones, why not get the higher wattage ones?

Discuss.

Thanks!

I would say the 100/80 is overkill and might blind other drivers too much. If you blind them they will hit you back with their brights and you both end up blinded. My 4Runner had the 60/55 and even that was pretty darn bright. I would start lower and only go up if you really think it's necessary. There are way too many cars/trucks on our roads with headlights that blind oncoming drivers.

If the lights are aimed properly and the pattern is well controlled, no reason why a higher wattage lamp will be a problem. They will be bright but not more than a good HID system.

Steve, I would look into picking up a good set of 60/55 bulbs, rather than the typically junky bulbs that come with most of the H4 conversion housings. I've read lots of guys on JeepForum that have good luck with the Philips / Osram bulbs. If you want something a little more interesting, I have also heard some good things about the IPF Fatboy bulbs (but I think they are a bit overwattage). They have a ring that glows when you turn your lights off (green or blue), and seem to throw some pretty good light.

Post up some pics of the conversion, as well as some night shots to show your output.

Hey Justin,
I wound up stopping by my local auto parts guy and asking him which H4s they liked, and he sold me a pair of 60/55w Wagner TruView bulbs. I said, "Are you sure I'll like these?" and he said he'd take them back if I wasn't impressed. So I dropped them in and they are amazing compared to the Phillips Long-life bulbs that came with the housings. Here's a pic of what the Rampage housings look like - very similar to a Jeep Liberty headlight, just rectangular, instead of round. These are also DOT approved, so I won't get hassled at inspection. I'll post a pic of the beam pattern tomorrow night hopefully.
