depends on what your looking for... low cost or excellentl ighting. Cause if your looking for low cost, the PIAA 40's may be your best option... looking for bestl ight, PIAA 80's hands down. I've got em, Rays got em, Ricks got em. The 520's are a good in-between model, in-between in cost,andbetter then the 40's but not as good as the 80's. Hope that helps! You could do like Ray did and get two sets on the roof, one set driving ando ne set fog's. That way you have some for the best long-distance light, and one for the best close up. Best to put fogs in the front not necessarily on the roof, but either way is good.
