    Default Is it possible to upgrade TC broís Triangle light to hi/lo beam

    Ive purchased the Triangle light from TC broís and Iím curious if anyone has figured out a way to run it with a hi/lo beam bulb instead. Do most people not worry about a high beam?

    Open the light and post clear pics of the socket, reflector etc.

    Should be as easy (or not) as replacing the socket but if you don't personally need or want high beam (I certainly would because if the working filament fails switching to high may get you home) that's your call.

    All sorts of LED upgrades exist too, some small enough to fit almost anywhere, but everything I have runs standard small HD buckets and I've not been motivated to replace my sealed beams.

    That socket and bulb may not be available in dual-filament configuration but it's a tidy way to go small.

    Next step is finding a replacement dual filament socket and bulb package with the right dimensions. Note the high temp insulation sleeves on the wiring. Ya can't substitute low temp wiring.

    Example site: https://www.1000bulbs.com/

    You can pull the bulb and figure out the base style then hunt similar size socket/bulb combos. I'd find dimensioned sketches from suppliers to get close and estimate using your existing reflector since I'd not want to modify that.

    https://www.bulbs.com/learning/basechart.aspx

    Expect several hours of internet searching and have some pics with a scale or ruler next to the bulb and socket handy to send to lighting supply tech support. Wattage and voltage matter as do lumens.

    When you have all the info you can manage on the existing bulb and socket, I'd ask here: https://www.candlepowerforums.com/vb/forum.php?

    Have fun and post results!

    TC Bros may be willing to tell you what style they use after you explain you want to mod the light and of course won't hold them responsible for anything.

    I think I’ve found a solution, once I get it and make sure it works I’ll report back. Thanks so much for the help!
