I purchased two pair of MTEC 194 super white bulbs for my corners and clearance strip at the end of Oct. this year. I had them in for a little over a month, and all four bulbs burned out........

I don't expect these type of bulbs to last forever, but less than 30 days is a rip........My Piaa exteme white bulbs were in action for well over a year before I decided to change them out.

Their Fog/High bulbs seem descent, but dont invest in the 194/168 bulbs......
Since its a PITA to change the clearance bulbs heed my warning....stick with a quality bulb.

Hope this helps someone else in the future

 

I hope my MTEC H4s stay alive... it's always such a dick to change those..
