just had my driver side headlight blow out and im looking for a replacement possible an upgrade bulb. I see high and low beam bulbs listed on sites like auto zone etc. Im going to replace both at one time. Which ones should i get (high? low?)? Had sylvania's.

 

the high-low is one bulb, idk about upgrades, autostores have them, but i never bought them, bought the cheapest ones i could
replace both sides at once, the left side you'll have to remove the battery box, its a bitch

 

my left side went in w/o removing the battery. its a tight space though.
i bought the expensive ultra's. they had a $10 or so rebate at the time. they were a little better than the standards, but not a lot.

 

huh, the problem i had is i could not unplug the left side from the harness, due to there not being enough room for my hands

 

it was the driver light that blew out and i got it out just fine lol. There was only one bulb in there so im assuming that it has the regular beam and the high beam in it? Im going to replace both of them btw.

 

Its obviously your choice, but Sylvania bulbs are junk IMO. I've tried their Ultras, their normal SilverStars, and their regular bulbs. All have failed me within a year, and none were much brighter than stock. They were a bit whiter, sure, but at stock wattage, white/blue/purple/etc. usually doesn't do any better than stocks, and has been known to actually be worse. (I am talking about normal halogen bulbs in our stock housings, not HIDs or halogen projectors.)

For everything except my headlights and fogs, I use GE bulbs. GE Nighthawk and Philips TrueVision, IIRC, are the best bulbs out there. Last time I checked, every article that compared the three companies said that GE and Philips outperformed the Sylvanias, and are about the same price.

I personally have tried all three bulbs, and if you prefer the stock yellow bulb color, you can't go wrong with Nighthawks made by GE, or TrueVisions (at least, thats what they used to be called) by Philips. O'Reillys usually carries both, or at least they used to around here.

If you prefer a whiter light (I do not recommend blue), want higher wattage bulbs, and you can find them, I run Nokya fogs (100w) and Eurolite 100w/80w high/low headlight bulbs. They are a nice white color without going to blue at all. If you run higher than normal wattage bulbs like I do, though, you will have to find HD bulb harnesses. I also recommend wiring the bulbs off of relays attached directly to the battery, as high wattage bulbs will burn up your headlight switch. If you don't run HD harnesses, you may melt your plastic ones because the stock wires are barely adequate for stock wattage, let alone more. Eurolites are made by Toucan industries, which is well known for making good bulbs. Nokya bulbs are OK... if I get a chance, I will replace them, because they aren't as white as I'd like. They just haven't burnt out yet or should any sign they will any time soon, so no excuse to change them yet.

There is also, of course, the HID conversion route.

The GEs are my favorite regular bulbs for turn signal bulbs, stop lamp bulbs, etc. They seem brighter than stockers, and I have had a set of GE tail lamp bulbs since 1 month of ownership on the truck, which is coming up on two years now, no problems. I don't know if Philips makes regular auto bulbs, I can't find them in my area if they do.
