i changed my old and tired 4300k philips HID bulbs with some brand new Philips 6700k HID bulbs and all was well until i went to look at my fuse box today to find both the fuses for the low beams were totally melted and melted some of the fuse box as well but somehow both my lights still worked fine. Now i dont understand why this would happen because the replacement bulbs are also 35Watts just like oem. Should i mabe replace the fuses for the lowbeams with a 20 amp fuse instead of the stock 15? thanks alot guys

with stock HID the fuses are supossed to be 15 amp... dont put 20s in there.

sounds like theres a problem somewhere else, I cant really imagine different bulbs making the ballasts draw more current, but if they're cheapo bulbs, you never know. A true philips bulb will say philips on the base, and wont be 6700K, the highest philips goes is 6000k and thats their Ultinon bulbs which are quite pricey.

Only thing I can really think of is that BOTH fuses were loose or not making a good connection... this would create all that heat but not blow the fuses...

philips makes both 6700k and 8000k HID bulbs as well. do some reasearch and you will find out. 6700k bulb is 85122fs i believe.

not a true philips, as they stay within the legal limits... their Ultinon bulbs are for euro use only, they're not DOT approved.

They also know that anything over 6000K is useless in terms of actual light output.

yea i know anything above 5000k which are the 85122+ bulbs is losing light output. I ordered ultinons and the guy sent me the 6700k's on acident nd i didnt feel like sending them back so i kept them. here are some 6700k's for you. they are for the japanese and i believe australian market.

they're not produced by philips... some aftermarket company got a hold of them and colored the glass. Notice the jap writing on the boxes... philips isnt a japaneese company.

85122 and 85122+ are not the color temp. The + is slightly dimmer so you can replace one without a large difference in output. I had a set of 85122+ that were 4300k and these are now in the S4. The ones in my car are 85122 and also 4300k.

85122 is the stock 4300k bulb and as the hours of usage go up on HID bulbs they actually shift up to higher kelvins and the 85122+ bulb or (color shift) bulb is actually 5000k so that it can be used as a replacement for a burned out 4300k so it can match the other old 85122 which is now closer to 5000k. I believe the 5000k are like 200lumens brighter than the 4300k.

The writing is in japanese because they are only legal aover there? does it really make sense to write in english on a product that is only sold in japan for exampple? the bulbs are still made in Germany but produced for other coutries

make sure its grounded really well. I had a fuse melt before and it was cause by a bad ground.

How long did you had the new bulbs in there before you checked the fuse box?

Whatever you do, don't replace the fuses with higher ampage ones.

Unless you want a fierce dash fire.
