Burned out foglights..AGAIN! - Toyota Nation Forum : Toyota Car and Truck Forums

***Cking*** · 08-30-2009, 04:24 AM

So first I changed my foglights to Mtech 4350k Foglights to match my 5000k white HIDs, but one burned out after a few days.

Given maybe I had purchased HID bulbs (i didn't) and maybe it was just a bad bulb, I gave Luminics 5000k Titanium White (High Performance Halogen Bulbs as it says on the box) a go. Within 4 days, the right one burns out. I forgot which Mtech burned out but it could be the left one or right now, either way, I have 1 of each bulb.

Now I really want some bright foglights, but they keep burning out..

The Luminics were recommended by a user here on TN, I usually drive with foglights on if my low beams are on. I don't night drive often, maybe 1 hour max. But somehow that still burns out my foglights....

Can anyone suggest a way to fix this? Or will I just have to stick with the futile stock ones

Did you touch the bulbs with your fingers when you installed them by any chance?

^ +1 if you get too much 'oil' on them, it may cause them to go, either that or something is wrong with the wiring/harness. I too drive with my fogs on 24/7 and my Nyoka (sp?) 3000k have held up for over a year and still going, I drive alot as well.

Keep your fingers off the glass bulb......My MTECS (High, Low, fogs) have been in for almost 3 years with NO burnouts.

Now to think of it I might have..

now i need a replacement bulb for Mtech 4750k and/or luminics 5500ks

lol. Just get the Mtecs again, and don't touch the bulbs! with your fingers

yea you must of touched it. mine haven't burned out yet at all. i don't drive much on them anymore. i see no difference on the road with them off or on. just use them for show and the real purpose of them(fog).

MrSo0h0o · 08-30-2009, 01:06 PM

yup you probably touched the bulb. the oil that is on your fingers is left on the bulb, and when it heats up, it causes a hotspot and burns out.

Good idea to wipe off bulb with rubbing alcohol prior to screwing into headlight assembly!

that's why i always wear gloves when handling incandescent or halogen bulbs. prevents this from happening and definitely prolongs the life of the bulb.

I don't think you should clean it with anything. Just don't touch any glass. It should be clean in it's container without contaminant.

Pawel062 · 08-30-2009, 08:54 PM

you can clean them and they'll be fine. i have touched by accident my d2s bulbs but cleaned them properly with special wipes i got from retrofitsource and they have been fine for a while now. the wipes are pure alcohol pads. i never touched any of my original bulbs though or my luminics.
