I searched for a DIY but I couldent find one. I havent wired them yet, so this will get intresting since I suck at that kind of stuff. Heres another pic of the truck more level. Also, I did not know the 500 ff's are bigger? I thought it was the same size as the origional 500's

 

Dirtydog made a DIY. It's in the offroad section. There are two kinds of Hella 500's parabolic and Free Form. They are both the same size. Here's the DIY: https://dodgeforum.com/forum/diy-do-...-properly.html

 

That is a good write up he did.

 

whats the difference between parabolic and free form?

 

Im curious as well, is one brighter?

EDIT: the regular 500's are a fog style beam and the FF's are a driving beam

 

Not quite, the regular 500's come in driving, fog and amber fog patterns and the freeform's only come in driving or what's known as pencil beam. The main difference is in the lens and reflector, normal driving light 500's use the lens to direct the light into a pencil beam where as the free forms utilize the reflector to direct the beam pattern keeping the lens clear and undiffused. Supposedly the FF's have a slightly better beam and produce a hair more light as a result of the more "Efficient" design.
