Hello, I have a 2007 Jaguar s type that is salvaged, trying to get it back on the road. I need all the lights to work, what is the tiny light bulb in the headlight assembly?? Thanks for the help!

 

Hi,
from memory it's a T10 bulb.
If you look at the socket, you cold confirm (I just assembled my S-Type and don't want to rip stuff off again to get to the bulb.)

Original is obviously an old technology incandescent bulb. I have thrown nearly all of those old bulbs out (inside and out) and replaced them with LED.
If I am not mixing something up, those are the T10 bulbs for the front park light, which I bought:

LED obviously uses way less energy, is unlikely to melt any sockets and is way brighter...

 

I have not gotten mine to come on, I will try trouble shooting in the park mode.

 

I am not sure, what your problem is.
Are your fuses OK? If your issue is that the frt. park light on one side comes on, and not on the other, normally, you would think that the problem cannot be a fuse, but at Jaguar, there are frequently separate fuses for left and right - which is something, no one would normally suspect...

 

I have not seen either side come on. If indeed that tiny bulb is the parking light, it’s on the same fuse as the turn indicator, and those work. I will start to trouble shoot, I will do the obvious and grab 2 new bulbs first. Lol! Would be a surprise that both are out, but I guess possible.
