Ok this may be a daft question but how to the standard t6.1 headlights work, Tonight I’ve changed my bulbs h7 and h15 drl bulb, I’ve just been out for a drive but when I put my high beam on it kills the main beam?? It just leaves the drl on , I've also noticed that the drl stay on with the main beam is this right ? Has anyone got a t6.1 that could possibly go and try there’s it seems strange to me?? Or can anyone tell me what the issue could be ?
