Hi there can anyone help please ?

When I turn ignition on the pre glow lamp lights up on dash for approx 2/5 secs then goes out, About 5 secs later it comes back on again the car starts and runs fine, the light will then go out again after a couple of miles, then if I turn engine off and start her again within 1/2 hour the pre glow light goes out as normal

If I leave car for approx 4/5 hours the same happens again regards pre glow light it will come on when I turn key go out and come back on again

Anyone got any ideas to what could be causing this I would be grateful for any help please

Thanks miller
