Ok I am putting Silerstar H13ST's in my truck today and I see that a lot of guys are running 9005 high beam bulbs in the fogs. The problem is i have round fog lamps and am worried about the heat cooking them, is anyone running the 9005's in their fogs????

 

I have been since the spring with no problems.

 

ive read ppl melted the lens with the 9005's in round fogs

just dont run them for too long and keep an eye on the lens

 

I'll try tem out and let everyone know how they turn out, but coming in to winter I'm not sure overheating is going to be that big of an issue. See what happens!!!

 

I just spoke with posstal (another member on here) Saturday and he told me his melted w/the 9005's. Winter or not, I wouldn't run them.

 

Ran them in my Excursion for 3 years( same size,just square) no problems.
Been running them in my `06 150 for 3 years with no problems.

 

Just put them in and ran them, driving around they don't get hot. But as soon as you go through town slow and stop they are really hot to the touch (not melting temperature but hot). Tomorrow I am going to leave them on all the way to work and see how hot they are after the drive. Jury is still out???? Anyone else have some input!!

 

I have an update, I drove to work with the fogs on for about half an hour. As soon as I got to work I got out and touched the lights....WOW they were smoking hot. Hot enough to burn your hands, I'll be changing them back. My drive is not stop and go but pretty straight 90km/hr drive, and the temp outside was 10 degrees C. So if you have round fogs do NOT run the 9005 bulbs in them!!!

 

I've been running 9005 in my round fogs for close to a year with no problems. They always come on with the headlights at night so they're on alot. I keep them clean all the time to prevent more heat build up. I'm also thinking that if they do melt I'll get new Hellas or something.

 

Don't do it. I ran them in my 06 Mark Lt. It melted my lens. Ran for less than 1 hr. Any advise on relacing them??? Thanks

 

I have them in my Charger fogs and no problems.

 

King, I can't recall the number - but you know they do make a SilverStar foglight bulb that is only 5watts hotter than the stock fogs? (looks identical and fits the same - just 5watts more powerful is all). I can't recall the SilverStar # - it's like 9145 or something - but have been running them in my '09 since taking delivery in March '09 with no issues. I run them all the time my heads are on - helps with the night vision. They are a perfect match for the SilverStar headlight bulbs too.

 

Will 9005's work in the rectangular fogs without melting

 

An update! My lens melted on both fogs. It took around a 1.5 years to do but it did. I thought after a month of them not melting they wouldn't. I guess the bulb got hotter with age after thinning some of the blue factory coating on the bulb.

 

Solution to problem ..........Put HID lamps (35W 6000K) in the round fog lights. I run mine all the time my heads are on and no melting problems...they run way cooler than halogens.
