I feel like I need to make a follow up to the installation of the LED headlamp. It has performed ok since installation, but is not as bright as it appeared for night driving. It is better than stock for long distance, but not as good for low beam flood. It is much better for daytime visibility to other drivers especially when the yellow halo is on.
There was so much RTV residue from the previous owner's T3 sealed incandescent headlamp inside the chrome MG headlight ring (bezel?) that it formed a thick 'gasket', so-to-speak and held tight when assembled with the new led sealed beam unit. The original spring clips that hold the original headlight ring to lens were missing.
Since riding it for a while it has started to shift around and I will need to go back in, probably using the original spring clips from another bike after cleaning out some more rtv from the headlight ring.
The LED headlight unit described above will fit inside the stock bucket after the spade connector is removed from inside the bucket. A hole may be needed in the back of the bucket to pass the new wires through. Some modification may be needed to hold unit tightly in place against headlight ring.
edit: It has barely even felt warm to the touch on the back of the assembly after a 1 hour ride in 70 degree F ambient, so it doesn't seem like heat will be an issue.
