Wondering how easy it would be and what parts would be needed to convert the Tourpak Lights to Stop+Tail.

 

A few things come to mind. How many bulbs are there in it? If there are only two they need to be converted from single to twin filament, with an additional wire to activate the brighter filament as a brake light. That may require new bulb holders. If there are four bulbs then simply rewire two of them as brake lights and install higher wattage bulbs in those locations.

I have a lid-mounted accessory light on my tourpak, which didn't come with any lights in the base, so I installed a pair of bullet lights underneath and rewired the whole thing. I now have three rear lights on it, plus three brake lights. I'm keeping quiet about my plans to outdo Retirementtoy..........

 

Just remember they don't count if you don't put the bike back together!!!

 

Phew!
