Which is the better choice?

Dunno on the serial numbers.
How are you having to “mess” with them?

 

And you’re sure the gasket isn’t double stacked? Also check the collar on the Micro as it’s adjustable.

 

Yeah seems off somehow. That collar locks into the detents on the backside of the lip.

 

I went w OPT7 LED and enjoy them
Felt LeD is long term and didn’t want a hid to go out and regret it

Light is better but I c any compare to hid
Find need my fog lights on, Also LeD to make a bigger difference
No unwanted glare to others noticed
I do understand purpose of fog lights but I run them constant anyways
