Bonneville America Forums Forums Technical Forums Accessories Tach lamp

Does anyone know the type of bulb in the stock TBA tach and where to get one? My light is out and I'd like to replace it. Thanks.

Silvergator, Had mine go out earlier this year. Not sure it was an exact match but I used a Sylvania 74LL replacement from the local auto parts shop. Works fine.

I didn't find a proper size bulb at my auto parts store (no 74LL) as used by MattyMo. I ordered a LED from Amazon described as "12.80 Volt T1 3/4 Wedge Base LED Light Bulb 0.24 Watt Color Warm White" for $6.00. The box is marked "LM0512WB-WW". I've installed it and it looks a little dimmer than the original and has a slight green shade but it may be fine. I'll followup after riding at night. Should last a lot longer than the incandescent lamp.

While at the dealer this weekend, I also bought a Triumph bulb. It is PN 2500085-TO301 and described as "BULB, INSTRUMENT, T6.5". The bulb is marking as Toshiba A12V1.7W. It also cost about $6.

Hope this helps if anyone needs to replace one.
