Cut the lenses using a Very New and sharp Junior Hack Saw, I chose this option after trying to do it with a Dremmel (that was far too messy and left gaps which needed multiple attempts with expanding glue.

Cover with Masking tape (lense protection on the offchance)
Mark backing and lense (I made simple scratches - that no one would see)
cut
do your bits inside
glue em back up
I also siliconed mine too
jobs a good un

looking good R00 .

A wee tip when cutting plastic lenses, you should heat them up with a hair dryer. This helps them from cracking.

Thanks Nis - would not have even thought about it had it not been for your most excellent experimentation !!!!

would of ended up payig for an overly expensive and far tooo blingy set of after markets.

Phil,

do it - go on you will you will you will, you'll look at it once done and quietly say to yourself, you know what "phil" it was worth all the bloody hastle

Believe me I do regularly,

even better when you have spare sets to work with, means no major rush.com to get em back into the car for usage.

go on stick with it !! and good luck...
