This is the direct link. H4.
Note the big bulge at the rear.,so make sure it will fit, plus it's wires, and original connector, in the space available.
It house electronics and a fan.
It needs more space than the original bulb.
It comes with 3 different plates, and I had to drill a hole in the headlamp housing (hidden area) to secure it.
The original waterproof boot won't fit, so you will have to make something up.
I had some Thin rubber sheeting and made a tube, inside it held the wiring from led bulb to original bulb connector, so watch polarity and wire colours,but you can cut off the origin connector if you want, which will save space.
I hope this is your problem, but I would still do some electrical troubleshooting.
