70? thats not much when you never replace them. factor in the times you will have to replace the cheap ones and your decision is now simple.
i bought two sets of the seconds ones at walmart, broke the glass outta 3 out of 4, do not get them, ones that are a little more pricey but well worth it, look at the hella 550, the have a driving beam and a fog beam to choose, they are like $80 for the pair
I don't think $70 is too pricey at all for lights. The round ones in my lower valance were $120 after a discount. The OEM fogs for my valance are $400 a pair not including the extra $100 a piece mounts.
