They actually work really well....
I've got them on my 91 holding it'* LP on... no issues.
But I don't think they'll give the effect your looking for.
They are very directional... it'* a very narrow beam. Two of them really wouldn't light up an area... more like have two directional lights. If you can sorta understand that.
They are great for LPs though.
I've got 4 I'm going to wire into the 97'* LP. I'm considering hooking them upto my brake lights. I think it would improve safety.... seriously though... I saw a SUV with a brake light inside the tail hitch.. it caught my eyes. Which was the whole idea of the high brake light.
