Upgrade your 1954 – 1978 Triumph motorcycle tail light with this 12 volt, positive ground, 1157 base LED tail light bulb. Works as both a running and brake light. Brighter and much more efficient than the stock incandescent bulb. Save the power your rotor and stator produce for more important things, like your ignition system, and reduce the draw on your charging system. This is a white LED.

Note that these LED bulbs only work with motorcycles that are wired positive ground, as these stock Triumphs were.

Note: There are no returns on carburetors, electrical items, full frames, hardtails or made-to-order items (such as magnetos) unless there is a manufacturers defect.
