I have an Issue with my Discovery 4, OS Dipped Beam Not Working, The Bulb Blew Recently and Have Fitted a Replacement Bulb (H7 Halogen) The New Bulb Comes on Briefly then Goes Off and Wont come on Again. Have tried the new Bulb in the NS Headlight and It works as Normal. All Other Lights on OS are Working Correctly (Full Beam, Indicator & Side Light). Has anyone any Suggestions to what may be the Cause
