I wanted to change them for LED ones but it's really complicated to access it

 

I changed mine with 68 smd white led. You have to remove the front wheels and the plastic trim behind the wheel. You will be able to reach the bulb but it's hard to change it and to squeeze your hand in there.

 

I had a Caravan before and sold it after getting this. (Already had another 4x4) Anyway the Caravan had ~ 6in plastic plate you twisted out of slots and removed. This was so you could reach through and access the bulb sockets and swap the bulbs. I had to change markers a few times and was able to after coming out of the auto shop having purchased a bulb. A few minutes and I was on my way with it working.

Why did they not do the same on these. Man I hate this new generation of engineers. I had to buy new kitchen appliances and everyone was engineered so bad I had to come up to speed what to look for. 3 electric ranges, 3 refrigerators, 3 dishwashers later and finally done after 6 months and mega hours of research not to mention driving hundreds of km.
