I’ve had Rugged Roads use the GS911 to fix the issue for me by recoding the centre light and the multifunction indicators. Much better than it was and they charged £30 to do it.
Having said that I am also getting a B6 fitted at the rear with a Hex ezCan and a pair of D3’s up front.
Personal preference - I want to see more up front and be seen more front and rear.
Maybe it won’t make any difference to my safety but it will make me feel better and the D3’s mean I will be able to see better at night.
