Hi Des
I have a 7th Gen diesel tourer.
I fitted this one
to the stop/tail and the exact same bulb to the indicators and reverse but obviously in orange and white respectively.
Like I said the stop/tail caused the glow plug light to come on, it would disappear after a while but come back again soon after usually when I put the car into reverse. The satnav screen would also show some interference (as shown in Javs LED howto thread). As soon as I went back to filament for the reverse the screen problem stopped but the glow plug light problem remained.
What happened with that is detailed here http://typeaccord.co.uk/forum/topic/1459-new-brake-pedal-switch/page__p__17029__hl__davemazo__fromsearch__1#entry17029. An expensive fix just for a poxy LED bulb.
The indicators worked fine but just weren`t bright enough. I have kept the ones at the front though.
I didn`t bother with the high level brake light.
I used 7443/7440 as referred to by a few people here and followed their links on Ebay.
Hope you don`t mind but I`ll put all this in the thread to help others.
