1920 T. The left headlamp works as it should. The right lights, but is dimmer. The bulb and socket are both good. Where do I look to resolve? Many thanks. Mistakenly listed in classifieds.
Brooks, it is usually an earth problem, caused by a poor ground between components. A wire soldered between the lamp socket and the body of the headlight will get around poor contact between the socket and the lamp body, usually caused by paint in the socket tube.
After that, you may need to check the headlight mounting in the fender iron.
Hope this helps.

Will give it a shot, Allan. Many thanks for the assist.
