Introduction: LED Taillight Motorbike


Hey yawl

A while ago I swapped my standard 12v 21/5w bajo light bulb for a LED light
because I was eager to improve my motorcycle. I didn't watch the specs of the LED light, which include the amount of lumen.

When I took a ride on my bike with my friends they told me, they had difficulties telling whether I was braking or not.
So I searched the Internet for a 'Better' bulb that matched or exceeded the specs of the standard bulbs, and pretty soon came to the conclusion that there weren't much options. made clear that there are a couple of problems;

- Not enough lumen (braking light).
- Not enough lumen (running light).
- Not enough difference in lumen between running and braking light.
- No effect on original reflector.

DO NOT compare the amount of lumen with a glow bulb and a LED bulb. To make a long story short: a LED shines in an curtained angle, and a glow bulb shines 360 degrees. The measuring is in an angle so they only measure a bit of the Glow bulb’s amount of lumen. That is why most measurements are false.

Step 1:


After a while I stumbled upon this website.

It is a Dutch website, so I hope you do understand it.


The specs of the most expensive bulb were outstanding on which I decided to take the risk of throwing 33 euros away.


In the photos you can see comparisons of bulbs (for what they’re worth).

Step 2:

The old LED bulb to the right, new one to the left.

And then finaly the result!
