I've been running MTEC 4350K H4 bulbs for a few weeks now. They're 60/55 = 130/110.

I bought a pair of PIAA Xtreme White 4150K H4 bulbs recently. They're 60/55 = 135/125.

Should I avoid using the PIAA???

Maybe I should have asked about the MTEC too before I installed them: should I avoid using the MTEC??

I'm just worried about the harnesses getting melted.

Just stay away from PIAA in general. They are known to be low quality coated bulbs just like the rest of them.

I didn't ask about the quality of the bulbs out there. I'm just asking if it will melt the harnesses.

if they're the same wattage as stock then why would they melt the harness. and why does 60/55 = 130/110?
