Light For car~70?

So I was looking around for a new light for my car and i cant really decide Curretly i have 4 solar forces they seem good but ive heard that Li-ion batteries dont do well in the heat. I was looking at the ITP a6 because it can use AA batteries but the build quality of it makes me hesitant. I m assuming a light that runs on lithium primary batteries would be best? maybe a surefire C2? that can be had for around 80 i think.. i just want a nice looking bright light thanks for the suggestions!



ohh als i would really like the possibility to run on LI-Ion batteries when i dont want to spend a ton on batteries... thanks
