Fellow B'villers

My left fog lamp went out last night. I haven't had an opportunity to look at it yet, but do you know if it'* just a bulb replacement or does the entire composite assembly need to be replaced like the headlight assembly?

Cost estimates?

Thanks

depending on the year, the replacement bulb would be either 880 or 885 (if they are stock fogs)
i wouldn't think it should be more than $10 for 2 replacements
