Siting of traffic lights

I reported this problem several months ago but no action has been taken. When approaching the M18 slip road to Doncaster from the M180 at the Tudworth Interchang a hig number of drivers are mistaking the traffic light on the services lane as applying to the M18 slip. I reported this as I had witnessed a number of near accidents due to drivers braking when this light is at red and since that time I have seen more near misses especially with foreign drivers although I have found myself going for the brake when the light suddenly changes even though I am aware of the problem. The incidents are happening when drivers who are aware that there is no restriction to the M18 find that the person in front who mistakes the light suddenly braking in front of them. The traffic light in question either neads a hood so that it cannot be seen on entering the M18 slip or re-angling so that it obvious it does not apply to the slip road
