Sticking glass to aluminium

Chaps... any glue experts in da house?

One of my little projects on the Camel Freelander has been to re-create the lightpod setup for the roofrack. I have sourced lights and had mounting rings manufactured and am nearly at the stage where I can assemble all the bits into a working unit. However I now need to stick the aluminium mounting ring to the light lens. The picture shows an original light unit which used steel mounting rings. The gluey bit is highlighted by the red box.

So.... the question... what is the best glue type stuff for sticking aluminium to glass? It needs to fill a gap of about 8mm. It needs to be weather resistant and have a good resilience to vibration. The original appears to use some sort of silicone sealant type stuff and has a very limited amount of squidgyness to it.

Any suggestions would be greatly appreciated.

Cheers

Dan :)

221 is a good all purpose bond/sealer, but for this aplication i would use 255
