Trying to figure out how to best improve the lighting for my 91 745 (no foglights next to the grill). I have seen options ranging from high $$$ all-up e-code assemblies purchased from europe with add-on relay wiring kits, to much less expensive replacement glass (e-code ?) lenses which are glued on to the original headlight assemblies. It seems like there are some in-between options, i.e. less than OEM all-up e-code assemblies, available for the 200 series cars, but I haven't had any luck finding them for later 740 series.
Bottom-line, I would really like to improve my lighting at a reasonable cost, and would greatly appreciate thoughts and suggestions from those who have been down this path before.
Thanks in advance for your help.
