Hi I have halfords HB3's fitted which I believe are single filament ? i have just noticed that I have no high beam on the right hand side

any ideas what could be causing this ?

It's gorn out  my PC is slightly to the right of Genghis
2012 HSE SD4 In Orkney Grey now gone, best car ever.

If you have a MY13 model and HB3 lamps which are single filament and dipped beam works then the shutter mechanism doesn't work. You may well have disturbed it changing out lamps.

indeed I do have a MY13

is it just a case of popping out the bulb and putting it back ? it was a halfords employee who swapped it.. then again the old bulb exploded and there was glass everywhere so perhaps there is a piece of bulb jamming it ?

any tips ?

2 minutes removes FL2 headlamp. ThenI would check for broken Glass. All FL2's (3) Gone

OK sorted it

it seems that the halfords HB3's ( the extreme brilliance ones) are slightly longer than the OEM Philips bulbs

meaning that the reflector was hitting the bulb hence jammed

this also accounts for the 3 bulbs my car has chewed through in the last 4 weeks...

i have ordered some OEM Philips bulbs to replace the halfords EB ones - currently the bulbs are set as far back in the holder as they will go and so far high beams work fine so who knows maybe they will last ?
