just stumbled onto this thread and wanted to give the OPs props for a quality
job. i've dropped E55s into 210 Depos and very pleased. started another one
using RS6 but haven't finished. this time, i'm pulling out the fresnel looking lens
and popping in a ZKW clone clear lens for a bit more pop. anyhoo, good job

 

Raymond, long time no see! Ive been wanting to do something like this forever. Im gonna hit you up when I do :P

 

sup, TT? sure, would be glad to help, though I've not done 203s yet. HID
retrofit projects are fun but requires some creativity...and precision but this
thread really goes a long way towards helping others trying to do the same
thing. removes some of the guess work. putting a headlight into the oven
for the first time is a bit scary. after that, it's fun.

the equiv thread for the 210 folks can be found here.

and, the wonderful reference earlier to HIDPLANET is a definite must-read.
