Many cars are now employing an electronic control system called CANBus, which can be a problem when using LED replacement globes as the system will give a globe failure indication. Being CANBus compatible, these LED globes don't cause these failure indications. This globe features a special "3D" type of LED lamp, which provides an extremely even, wide light output that is very similar to a normal globe in style and appearance. This makes them a perfect replacement for interior lights, and automotive lamps where the light fitting has a lot of "clear" elements making other LED globes unattractive to look at. Powered by 12-16VDC, and suitable for off-road use only. Light Rating Lumens : 120lm Illuminated Colour : Cool White Beam spread : 360Deg Standard Fitting : 41mm Festoon Length : 41mm Diameter : 11mm Required Voltage : 12V, 16V
