Car Forum / Hyundai Cars / May 2008H7 bulb still failing with reduced voltage
A H7 bulb failed in my modified 2002 XG350 after 2 months. A 10 amp diode had been placed in the headlamp circuit that reduced the voltage at the bulb to 12.8v. Apparently, this modification has not extended bulb life by any appreciable amount. At this point, I'm starting to look into an HDI system that uses bulbs with no filament. Anybody have one of these? I see you can get them for around $75 on Ebay. Any recommendations? Dan I'd be concerned about the reliability and durability of the parts in an HDI system you can purchase for as little as $75 - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm > I'd be concerned about the reliability and durability of the parts in any > HDI system you can purchase for as little as $75. Additionally, the reflectors in the headlights are not designed for HID bulb and the result is a poor beam pattern that creates a lot of glare for oncoming drivers.

This really does raise questions about the H7. Anyone know what other cars use H7, and do they suffer the same short life? This whole H7 thing has take on a certain intrigue...  Signature-Mike- mmarlowREMOVE@alltel.net I haven't been following thread as closely as I might have, but is it one H/L socket involved very time or both sides? If one side, I'd suspect the socket. examine for corrosion and proper contact and perhaps replace the socket. > heck, maybe both side are buggered up. (I had a car which ate running lamps-was a socket) Numerous people, not just Hyundai owners, notice a seemingly short lifespa for H7 bulbs. It's been my experience that many H7 bulbs fail within th many manufacturer's new vehicle warranty periods - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm "Mike Marlow" <mmarlowREMOVE@alltel.net> wrote in message > Bummer Dan.

I found this http://www.luminicsbulbs.com/h7_bulbs.php H7 bulbs fit the BMW 3-series, Audi A4, Jaguar S-Type, Land Rover Discovery, Mazda 3, Mercedes-Benz C-Class, Mini Cooper, Toyota Celica, Volkswagen Touareg and many more. H7 bulbs are one of our most popular applications and Luminics bulbs yield high quality and long life. In addition, I found bulbs listed from $6 to $48. Quite a price spread. > "Mike Marlow" <mmarlowREMOVE@alltel.net> wrote in message >> Bummer Dan. Good follow up though. Thanks for that.

If you haven't looked at Daniel Stern's site, you should check it out as it's very enlightening (no pun intended). > In addition, I found bulbs listed from $6 to $48. Quite a price spread. I've tried several of them and haven't found any correlation between price and bulb life. I'm now on the least expensive bulbs so far - $20/pair Hella standard bulbs - and we'll see how they hold up. They're rated for much longer life than any of the others I've tried. > GUEST wrote > A H7 bulb failed in my modified 2002 XG350 after 2 months.

Could b bad or loose contacts, voltage surges in the system for some reaso or some other unknown reason My experience: Have 02 Sonata and it has never blown a bulb anywher and it has H7s. Have 15 year old Integra and it has all the origina bulbs Once had an house air conditioner that kept blowing its fuse. It wa one of those that clip in similar to fuses in the old cars. I ben the holders in so they held the fuse better and it never blew anothe fuse Good luck,,,Luk |
