We have new fiat ducato based van and rear lights are Led from manufacturer but fronts are standard. (Apologies if already covered here)
If we fit osram Led W21 will these cause lamp failure and what have others done for Led H7 type upgrade. Secondly looking at fitting rear sensors but lights are Led will this cause issue if I can work out how to get apart. Have camera but would also like audible warning too.
