When I had my OEM fogs put in, I took my HIDs and test the fittment in the housings for the fogs. I just thought the bulb was to long and it just felt hot by the time they got to temp and the blue was out of the light output. I just felt safer putting in the H11s.

Of course, this is just me and my car, I don't think I've seen anyone talk about melting anything with HIDs in their oem fogs... YMMV!

 

HIDextra sucks by the way. You'll be returning them within a week once they break.

 

^maybe it's a hit or miss with hidextra, my hid's have treated me well for 2 months now

 

where did u guys put the ballast for the HID fogs? I think im just going to settle with some PIAA's or Nokya's.. im not that big on it since the HIDs im going to get for my headlights will help more likely lol

 

hey i recently just put 8ks on my 2011 scion tc. Love it. I did put the relay harness on it as well.

 

Where did you buy your relay harness? I need to buy 2. one for my low beams and 1 for my fog lights

 

^you don't need a relay harness for your low beams. Only 1 for the fogs. I got mine when I bought my hid's from hidextra.

my low beam hidextra's have been working well for 2 yrs now, so no problems here. Once in a while 1 won't turn on the first try, but just turning it off and back on will fix it and I haven't had an issue for a while now.

6k HID's with normal ballasts in my low beams
6k HID's with slim ballasts + relay harness on my fogs

 

I have both 6000K in my lows and foglights and have had zero issues.

I use Meng motorsports.

If you use a respectable company, you shoudlnt have a problem
