Headlamp washer reservoir part number

.. the part number for the washer reservoir that would have been used for a genuine factory installation of headlamp washers?

The headlamp washer pump used on genuine Defender headlamp washers is the same as used on the Disco 1 and 2, RRC, and several other models, but it is a larger diameter motor than the front and rear screen washer pumps used on the same vehicles. It won't actually fit in place of either the front or rear pumps on a normal Defender reservoir (which is a shame, since I had intended to fit in in the empty rear pump space on my truck).

Only a Defender reservoir fits a Defender, so for example a Disco 2 reservoir simply won't fit. It would be possible (there is space, just) to open another hole in a Defender reservoir to fit the pump, but before I did so I wondered if anyone knew what reservoir was actually used by LR for the purpose.

Does anyone on here have a Defender with a genuine factory fit headlamp washer system, and if so is there any chance of a photo of the reservoir?

Many thanks!

This is from the list of numbers I gathered when looking to add factory headlight washers myself

Fantastic, many thanks for the info!

Mind you I've just looked up the price and it is just under £100 for the washer bottle, and that doesn't even include the lid!

No wonder it wasn't a popular option.

there must be other options. I could take a pic of one from the range rover if you like? Also has level sensor

I think the simple option is to mount the pump on the side of the standard reservoir, which has an advantage in that the headlamp pump will be a little higher than the screen pump, so the headlamps will run out first thus warning of low fluid.

There is so little space under the bonnet that I don't think a RRC or Disco2 res would fit (I have a spare D2 res), but thanks for the offer of a photo.

Are you going to have them so they only work with the lights on? 2002 90 Td5 Station Wagon

I haven't yet decided how I will do it, but it will be one of the following:

1 ) Wire them so they squirt with the screen washers if the headlights are on.

2 ) Wire them so they are on their own squirter button but only squirt when the headlights are on.

3 ) Wire them so they are on their own squirter button but squirt whether or not the lights are on.

4 ) Combine 1 and 4 for the best of both worlds.

I wasn't planning to bother with a timer relay, at least not initially.

I suspect that they'll empty the reservoir fairly quickly.

For £100 plus other bits and fitting, you could just lean out of the window at traffic lights and pay pedestrians to wipe the headlights!

Isn't that what the Squeegee gangsters are there for?
