Brand new product for 2014!
This 19 LED array is the brightest 6 volt stop and tail light unit available and provides excellent illumination of the Lucas 525 style of rear light fitted to many classic motorcycles and cars produced in the mid-1950s. It is compatible with both positive and negative earth 6v electrical systems with internal circuitry to automatically adapt to the motorcycle’s polarity.
It is a dual intensity lamp which means that all of the LEDs illuminate for the tail light function and then they all become even brighter when the brake is applied. This gives excellent illumination of the rear lamp with a clear difference between the tail and stop light functions.
The light unit is comprised of a circular array of 19 bright red LEDs. We also have a white LED version available, however we recommend the red LED version for use with the Lucas 525 rear light unit as it gives superior brightness and makes it glow a deep red colour which is very visible to following motorists. The white LED version gives slightly better number plate illumination with some styles of rear light, but not with the Lucas 525 type so we suggest using the red LED version for this application.
The LED has the standard BAY15D dual contact offset pin base which is sometimes also known as the 1157 fitment. It has been tried and tested installed inside a Lucas 525 rear lamp and has been found to fit perfectly. The large circular array of LEDs gives excellent visibility of the stop and tail light functions which is as good, if not actually a little better, than the standard filament bulb.
The Lucas 525 (L252) tail light
The Lucas 525 tail lamp (sometimes also known as a L525) was a popular rear lamp fitted to countless motorcycles in the mid-1950s. It was used by a number of manufacturers including BSA, AJS, Matchless, Ariel, Royal Enfield, James and Triumph amongst many others. It uses a twin filament bulb to give both stop and tail light functions.
It looks very similar to the slightly later Lucas 564 (L564) tail lamp but is discernible by its more tapered lens. Lucas stopped producing the L525 lamp shortly after the slightly larger and squarer L564 model was introduced and so many motorcycles were swapped over to using the newer model.
Both the Lucas 564 and 525 tail lamps are popular for fitting to modern motorcycles such as the various new Triumph Bonneville models to replace the somewhat ugly stock tail lamps and give a more classic look. They are often also supplied with the various ‘fender eliminator kits’ (FEK) and modern reproduction units are widely available.
Please note: This item is only the LED ‘bulb’ upgrade and does not include the Lucas rear lamp unit itself.
