I am adding 2 tail lights on my 1918 and want to use 27 drum lights.1927 brackets have the wrong angle on them as the lights sit at an angle.Any suggestions and pictures on what to use is appreciated.
Lang's sells a "right hand" fender bracket for that purpose (Cat. # 8785R).
That bracket is made for the wider flatter crown '26-'27 rear fenders, but might work on the more narrow higher crown earlier rear fenders.
The bracket then accepts the special drum license plate/tail lamp, or the one piece tail lamp plate bracket of the '24-'25.
Have the right side repro fender bracket on my T.
How about making taper shims to go between the bracket and the light or between the fender and the bracket. Probably best between the light and bracket as they wouldn't be as conspicuous.
