The smallest LED rear lamp unit available!
This super compact 12 volt LED light is the perfect choice for installation in tail lamps where space is limited, and in particular the early pre-war Lucas MT210 and MT211 rear lights. It measures just 31mm long and 19mm in diameter at its widest point, so it is significantly smaller than all of our other LED units and also barely bigger than the BAY15D (1157) base itself.
The lamp is a dual-intensity LED array which means that all of the LEDs light up for the tail light function, and then they all illuminate even more brightly when the brake is applied. Clearly the brightness of this compact LED unit will not be as much as the larger models we offer which have a greater number of individual LEDs. It does however provide more than adequate illumination of small tail lamps for a fraction of the power consumption of a conventional bulb.
It has the standard BAY15D dual contact offset pin base which is sometimes also known as the 1157 fitment. Note that it is only compatible with negative earth electrical systems.
We have two versions of this LED unit available with either red or white LEDs. We recommend the red LED version for most applications as this gives a brighter red light through the red plastic lens of most tail lamps. The white LED version isn’t quite so bright as some of its output if filtered out by the red plastic of the tail lamp’s lens and it also makes the lamp glow a more pinky colour. It does however give better illumination of the rear number plate if that is a concern for you. The red version is also a little cheaper. Both versions look identical when the LEDs are not illuminated. Click on the ‘Help me choose’ tab above for more information concerning the relative merits of using red or white LED lights.
