i got LEDs to work in the side lights without bulb out warning
some auto electricians might frown at how I did it but hey they they look 100 times better than even the best blue coated PolarG ones
I wired a set of universal side repeaters into the side light wiring and keep the ordinary bulbs in these outside the headlamps (good for checking oil level in the dark

) then put the LEDs in the headlamps
bingo LEDs working, no bulb out warnings
tip No.2 once you get the side lights out wrap some black tape round where you will grip them for the next time you want them out, a lot less painfull on the fingers
