Bulbs all dead straightforward except the speedo. Some fiddling with contacts. Top Tip, invest £4 in a pair of forceps from Amazon to help extract insert. Once in a great enhancement.

Arrived very quickly and well packaged.

Fitting is the big issue
1. the clock is a sealed instrument the light cannot be changed without disassembling the unit - NOT A GOOD IDEA
2. the temp & petrol gages are very easy to fit and the process pretty obvious
3. the speedometer has two bulbs (the larger ones in the pack) buried in two holes in the back of the speedo. It proved necessary to remove the speedo (very easy in the TD5) but getting the old bulbs out and new ones in can be a struggle. You will need a very strong pair of tweezers or much better the type of straight forceps used by a fisherman to remove a hook from the fish, these worked perfectly for me whereas I could not get sufficient turning force using tweezers. Remember LEDs are polarity sensitive so wire up the spedo and check the bulbs work before re fitting into the dash.

TRICKY GETTING THE SPEEDO BULBS OUT AND IN BUT ONCE ALL FOUR LED'S FITTED HAS BRIGHTENED UP THE DASHBOARD SO YOU CAN ACTUALLY SEE THE DIALS OF A NIGHT!
