/diy/ - Do It Yourself

That's the newest burjo börö system. From left to right
1. stop
2. proceed
3. proceed 35 km/h
4. proceed, expect stop
5. proceed, expect proceed 35
6. proceed, expect proceed
... and so on.

Single white is "proceed carefully", single blue is "no signals". (I didn't have any white/blue leds at hand so I used green/yellow instead).
