Hi Folks,

             I fitted an upgrade kit and all was great for months then all of a sudden the O/S light went off. I thought it was the bulb but I could not get a replacement locally so I bought another kit. After fitting it the lights started working and I thought great, but half a minute later it went out again????? if I switch the lights off for 5 minutes they start up again but the O/S fails again shortly after.Can anybody give me some ideas as to what’s causing this issue.

Did you change the ballast when the got the new bulbs? 

Hi,

    Thanks for getting back to me. I changed out the whole kit including the ballasts, the bulbs come on and the N/S stays on perfect, but the O/S only stays on for about  20 S seconds then goes off. I have had the old set tested and it works fine as does the replacement kit. The strange thing is that the old kit was working fine for months, so I was wondering if there might be a problem with a relay?? as it starts up ok but then fails, theN/S remains on. I have replaced the fuses so I have run out of ideas.
