Royal Enfield 144514 – Speedometer Bulb 12V 3.4W for Standard 350/500, Electra 4S/5S & Machismo A350/A500 – Genuine-Type Replacement

Royal Enfield part 144514 is listed in the OEM catalogue as “SPEEDO METER BULB 12V 3.4W” – the small bulb that illuminates your speedometer at night. Bike-Parts-RoyalEnfield explicitly catalogs 144514 – SPEEDO METER BULB 12V 3.4W as a genuine Royal Enfield spare, identical to the bulb fitted at the factory.

144514 – SPEEDOMETER BULB 12V 3.4W ENFIELDGP, and clearly lists model usage as Electra 4S (2005–2010), Electra 5S (2005–2010), Machismo A350 (1999–2005), Machismo A500 (2009), Standard 350 (1995–), Standard 500 (1990–). The Spares Company also lists “SPEEDO METER BULB 12V 3.4W 140225 (‘144514)”, confirming 144514 as the classic Royal Enfield speedometer bulb reference, often superseded by 140225 in newer packaging.

This is a 12V, 3.4W low-wattage bulb designed specifically for instrument illumination: bright enough to read the dial, but not so bright that it causes glare. Perfect when your classic Bullets/Electras have a dead or flickering speedo light, or during restorations where you want the correct-spec bulb instead of a random substitute.

For other Royal Enfield models that use a 12V 3.4W speedo bulb, it can often be used as a universal replacement, but we only guarantee direct fitment for the CI/AVL models listed below.
