Picture of LED Caravan lighting
One of the biggest drains on your caravans power are the lights. Each of those twin fluorescent fittings draws 8 watts from the battery, that's 16 watts each light, that does not sound a lot until you start counting up the lights in your unit.
How about being able to have all of the lights on and still not draw as much power as one of those fittings? Ahh enter the humble LED..

Step 1: Tools

First you will need some tools;
A soldering iron, flux and solder
A thin bladed screwdriver
A 'Philips' or cross headed screwdriver
A cordless screwdriver and 4mm drill bit
A multimeter
A quantity of 4mm clear plastic ties - DO NOT use black as these will show up when the light is on! (To work out how many ties you need, if the lights are twin tube, you need six for each one)
A pair of sharp snips to trim the tails off
Extra gas for your soldering iron, just in case!

Step 2: Removal

Right so now we're ready to start. Unscrew the two Cross headed screws securing your light and gently pull the wires through until you expose the connectors. Make a note of which one the red (positive) wire goes to and unplug them both.

Step 3: Rear View

This is what the back of your light will look like. Remove the sticker covering the circuit board and gently prise out the tubes ONE at a time, ensuring that you hold the metal parts and not the glass, if these shatter the resulting shards are very nasty!

DO NOT be tempted to just solder your LEDs on here, as there is a transformer on that board that WILL fry them - as a friend recently found out.. :o/

Hi Windy just done my caravan lights, spot on your instructions were easy to follow and the job was so straight forward , well pleased with the results cheers Bob

Hey Robert, you will definitely notice the difference in brightness and in battery consumption! Plus your neighbours will be wandering over to see what you have done, we get it all the time :-) See you out there..

Hi windy,

Thank you for a wonderful project that I am attempting to complete, I am a novice caravan owner and love the idea of going off grid and using low watt LED's to supply my light requirements, however I am stuck... I have removed the two nasty power hungry tubes and replaced them with kinder LED strips and have connected both ends, now how do I wire in the switch?, picture supplied/

Hey great to see another convert - trust me you will notice the difference! Ok the idea of the switch is to interrupt the flow of power, personally I would take the red and black wires and attach them to the red to red and black to white on the switch. Make sure you tape these connections up before refitting the light, I forgot the first time then spent half an hour looking for the right fuse! Hope this helps - Windy

There is one big problem, if the led strips one uses are not signal interference free they will effect TV and Radio on board to some degree!

Thanks for the clear instructions.
Could you give me any links or advice to buying the right LED strips please?

Hi, see for a range of LED lights - it's a new business with an expanding range of LED lights which were inspired by a self build :-)
Windy Miller (author)  ledshed2 years ago
Thanks ledshed! Definitely a good business to be in ;o)
Certainly is and one that came about by coincidence more than anything else - after struggling with lights on my own conversion, I had a few left over and decided to put them on Ebay, the demand was so high I ordered more stock and started from there :-)
Windy Miller (author)  ledshed2 years ago
Nice one! I'm surprised how many people come over to us when we're off camping, just to ask about the lights. One bloke came over last weekend and shook my hand, he had followed my advice and changed all the lights in his motorhome. He then went off and spent three weeks in Ireland off grid, with just a small solar panel. He could not thank me enough. :o)
Windy Miller (author)  pedixi3 years ago
Sorry for the late reply, I've been busy starting a conversion on an ambulance which is soon to be our camper!

A quick search for 12 volt led lights on your favourite auction site ;o) will bring up the flexible strips that I use. Price varies greatly so read the small print and always go for the 'Bright white' option as these have a very slightly blue cast. The other option is the 'warm light' which is rather yellow by comparison and really not strong enough to use as lighting, but good for soft or background lights.
I tend to go with the cheapest on the day, after checking their feedback obviously!! and have never yet been let down.

Hope this helps a bit

Update: We have recently purchased an Ambulance to convert into an RV, first job was to replace the lighting with LED's instead of the fluorescent tubes! Found some on ebay from China @ £1.99 each with postage, these are now fitted and are so much brighter than the old ones!!

Superb and simple - I saw this, bought the parts and completed the job with the 5 fittings in my van over a rainy Sunday. Excellent instructions and a nice end result. To maximise light output, I also installed two LED strips even into each of the single tube fittings - give that the strips I bought were £1 each, it was a cheap job too.

Many thanks for the inspiration sir.

Windy Miller (author)  glennonjd4 years ago
I'm glad that others are benefiting from my experiment! TBH we've never regretted it and still have a smile when people notice how good our lights look and ask how they can do it.

The pleasure is mine

For a person who loves caravanning, this would be an AWESOME X-mas prezzie!!! I'm so gonna try it!!
Windy Miller (author)  Squabywokl5 years ago
Hey I'm glad you like it :o) Some naysayers may tell you they are dimmer, trust me when I say they're talking .... erm rubbish ;o) Any questions, give me a holler! Windy

Major hack. This also provides a great template for those who want to lower the power consumption in other vehicle types and solar installations, such as RVs and the like.
Windy Miller (author)  bruc33ef5 years ago
Very true, I've heard that some people have also replaced their car bulbs with an LED equivalent, but I am unsure as to the legality of this route, Thanks for the comment Windy
