Looks like a winner to me. Very Nice write up and something I now want to do.
Since you had a closer look in one, maybe you can give me your opinion concerning the shield: 1) What is the purpose of the shield; too push the light back off the reflector and focus the beam more? 2) Would it be beneficial to have the shield or a modified version of it still in the light? 3) The 510 comes in Driving and Fog; is this just a different bulb/lens/reflector or is it a different shield?
Thanks again for the idiot proof write up; wish they were all this clear.
