Hey guys I found this while I was looking at some rides on cardomain. The guy replaced his opera lamps on his hearse with new limo side marker lights.
They look pretty good! And they are much brighter......

but is this an easy task? Has anyone done it?

His hearse is a Buick LeSabre so will that affect it vs. a Caddy?

no that shouldn't effect it
