Can anyone tell me if both bulbs are meant to light on the Tiger and then both are brighter when brakes are applied. The bulbs both have twin filaments but only one appears to work when switched on and then other comes on when brake applied? I haven't put that very well! Basically do both sides function the same and are the bulbs interchangeable?
Thanks
They both should be on, and they both should brighten when you brake. Basically, you have a filament gone in one which is not unusual, my Trident and my Tiger both seem to eat rear bulbs. Carry a spare (wrapped in bubble wrap) - it always impresses a picky cop if you're stopped.
Good plan, many thanks for the info.
