I agree. Most OEM foglights are really pretty terrible. The ones in my Disco are actually decent. One of the few I can say that.I'm not completely torn up about this. I've never seen foglights that actually work as well as I'd expected. That means that either none of the foglights I've used have been worth a damn (they have all been whatever came from the factory), or else foglights aren't all they're cracked up to be.
I believe the bar Crikey posted is for the earlier truck 84-96 vs. the later vehicle which has a few minor differences relating to the returns (or wings) being altered for the slightly revised Jeep bodywork.
