I've used these... https://www.amazon.co.uk/Osram-1457...&psc=1&ref_=ppx_yo_mob_b_inactive_ship_o1_img
Though while they do work, the load is insufficient and I was getting lamp failure warning (glow plug light). I'm currently running one of these and one tungsten while awaiting a proper solution.
Hello,
and what LED headlights have you used?
Thanks!!!!
