Awning light replacement (1 Viewer)

[Gellyneck]

This is the awning light unit on our AT Savannah and a number of the diodes are failing \ have failed.

Having had a close look at it and searched through the threads on here I'm still struggling to see how it comes off the side of the motorhome.
Anybody replaced one of them or any idea how it does come off?
TIA.

It looks like you have to tease the two end caps off to revel a screw at each end.
I would imagine that AT have fixed back the light using a non setting mastic to stop water ingress where the wiring goes through. If this the case the warm the light unit up with a hair dryer at soften the mastic.
Here's a photo of the back of the light unit i found that should give you a clue to the way the end caps fix on.

Brilliant Paul
From my interpretation of the "new" unit it looks like the end caps may slide off whistle2 from the ends of the frame. Will have a wee look see later.
Many thanks.

Still waiting on the weather improving to have a look see but have sourced a supplier for a replacement unit in the interim.
Assuming it's on with non-setting mastic I'll be cleaning this off and would need to replace. What's your thoughts on a suitable mastic?
TIA

I always keep a box of W4 Mastic Tape handy for jobs like that, and have used it with good success. It comes in varying widths, and usually in grey or white.

Cheers,

Jock.

When I changed our roof vent I bedded the ones in on Silaflex Lastomer 710, but and non setting mastic strip or from a frame gun will do.

Many thanks guys.
Will have a look at both options.

I have to say Gellyneck, having taken the advice of a caravan repair workshop to use the IDL 99, on a particular resealing job, it was unsuccessful, whereas the W4 tape was extremely successful.

The other advantage of the tape, is that it doesn't appear to go off over time, and you can cut and trim to shape before applying, ie, if what's left over is too wide for a another wee job, just cut to the width required.

Good luck.

Jock.

What's that saying about great minds? The very thoughts I was having.
One question, if I may. What's the thickness of the tape and do you "squash it down" under the job? Okay, okay, that's two questions!

Jeez, just realised what an insult, comparing our minds! SORRY!

 

[JockandRita]

Aye, and so you should be.

TBH, I can't remember if it comes in different thicknesses, but it easily beds in and settles. You might need to re tighten any attaching screws or fixtures after a few weeks, especially on roof lights.
If not thick enough, double up on the layer.

Cheers,

Jock.

 

[Gellyneck]

If not thick enough,

Obviously, I'll pass that criteria no problems! (cheeky bu**er)
Cauld and dreech here, AGAIN, this morning so postponed party2 until mañana.
By the way things are going there's gonna be plenty of time left to complete the list.

Hi Paul

Update \ feedback on replacement of our awning light. Also, a quick guide for anyone else who may need to replace.

As a result of your previous post on a replacement unit I ordered this online.

Given the recent excellent weather, obviously, we've been touring all over the place so only got around to fitting the new unit today. Aye right!!!!!
The supplier sent the wrong unit (the longer version!) initially and correct replacement arrived today.

As it turned out the job was a fair bit easier than first envisaged.
The area circled in the picture below shows how the end caps attach to the body.

You slide a thin flat rod into the channel and (hopefully!) this depresses the round pin next to the fixing screw holes.
The end caps then slide off outwards from the main body.
Unfortunately, because the plastic was fairly brittle these pins broke off.
In our case you only needed to remove the right-hand end cap. Obviously, I removed the left-hand one first!
Once the end cap was off I cut the feed wires which are routed through a sealed hole through the side of the motorhome, stripped the ends and soldered these to the wires shown in the photo.
As the led light strip slides out the end of a channel in the light body I just removed the faulty one and slid the new one into the original light body! No need to try and remove the light body from the motorhome wall.
You then just slip the end caps (new) back on and you're done!

Only minor downside of this is that the original light body had yellowed very slightly but don't really see the shade variance. The new caps will, of course, yellow over time. The body is aluminium with the caps being rigid plastic.

Many thanks for your pointing in the right direction for the correct unit.
