I have a pair of XL80s (along with a bespoke BD lightbar) fitted to my car. Very impressive lightsI have 2 pairs of Baja designs. XL80s when I need them and Baja S1 with which I replaced my OEM (Read useless) GSA fog lamps.
The S1 are bright as hell and give a fantastic beam. They do make yellow covers for them. Maybe I will see if they are available and report back the difference.
