PIAA (and others) make some nice ion models which give you the yellow. Higher cost though but human eyes see amber the best so it's great for bad weather areas. If just for looks try yellow bulbs first for lower cost.
I need to replace my fog lights and am not sure how to determine which aftermarket sets will fit. If possible, I am looking for a set not much over $100. Does anyone have any suggestions? And, where do you get the stone guards? Thx for any info
