Derek Uzzell Posted February 1, 2013 Share Posted February 1, 2013 I don't know which bulbs are fitted in the under-cupboard lights of your Year -200 Auto-Trail Cheyenne but, if your lights currently have what look "like car bulbs", that's what they probably are. This website lists a wide range of 'ordinary' automative bulbs and their LED equivalents. http://www.ultraleds.co.uk/led-product-catalogue.html If your present bulbs have a bayonet fitting, you'll need to identify the fitting type (and the bulbs' wattage, which should be legible on the bulb). If you are lucky a direct LED equivalent will be available: otherwise you might need an adapter.

lennyhb Posted February 1, 2013 Share Posted February 1, 2013 If they are car type fitting be careful of the replacements you buy some of the after market car bulbs have loading resistors in them, fit them and you won't get much power saving.

Cliffy Posted February 1, 2013 Share Posted February 1, 2013 I removed my over cupboard strip lights and fittings and replaced them with LEDs in strips. You just cut the strip to the lengths you require and solder on a switch live and neutral wire to one end and stick them on to the units. They come supplied with a sticky backing.. It is amazingly easy and really cheap. You can connect them to a twelve volt battery to see what they look like before you fit them and if you don't like them the low cost means you can keep them for another use. I gave my leftover bit to my mate who uses them to light his garage. These are typical but are waterproof,. you may not need them to be waterproof. Non waterproof are cheaper still. http://www.ebay.co.uk/itm/5M-LED-Strip-Tape-Light-White-Lighting-SMD-1210-12V-/220789123023 Link to comment Share on other sites More sharing options...
lancepar Posted February 1, 2013 Share Posted February 1, 2013 First thing to do is get the current bulb out and see what it is, my guess would be a G4 10w Halogen, there have been some threads on here regarding LED replacements. Here is one. http://www.outandaboutlive.co.uk/forums/Motorhomes/Hints-and-Tips/Interior-lights-disassemble/29386/ HTH B-) Link to comment Share on other sites More sharing options...
camperadi Posted February 2, 2013 Share Posted February 2, 2013 I asked a similar question recently. The thread can be found here. http://www.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/is-it-more-complicated-than-it-1st-appears-/30011/ I had some very informative replies. In the end I didn't buy from ebay. Yesterday i ordered from Aten lighting with free delivery and as yet my bulbs of different types havn't arrived. There website is very useful and gave me the infomation i needed. I wiil update my original thread when i have had time to try out the new bulbs.

These are not uncommon (in halogen format) in motorhomes, but they do not look anything like "car bulbs". Casting my mind back to when I owned a 1996 Herald, this had under-cupboard reading-lamps that had common-or-garden tungsten-filament 'car bulbs' in them. The original bulbs were this type http://www.spares2you.co.uk/12v-15w-Bulb-W4-37552 and, when I added a couple of extra lights, I vagely recall swapping the tungsten bulbs for halogen look-alikes. If jordano has this type of bulb, then (as lennyhb warns) care will be needed to ensure that an appropriate LED replacement is chosen. Link to comment Share on other sites More sharing options...
camperadi Posted February 3, 2013 Share Posted February 3, 2013 Sorry was not clear on my post. I only bought 1 mr 16 bulb. What i wanted to do was draw attention to a Atens website because it has all sorts of different types of led bulbs some of which are car types. It also offers the strip type mentioned and the opportunity to cheaply replace a bulb holder so that you can replace the bulbs to a more common type. I went on to purchase back pin and side pin g4 bulbs and replaced the ceiling light bulbs instead so that less shadows would be cast. I should have made this clearer on my previous post.

Derek Uzzell Posted February 4, 2013 Share Posted February 4, 2013 Jordano needs to identify which bulbs are currently fitted to his 2000 Auto-Trail Cheyenne. Once that has been established, and he relays the information to this forum, it should be possible to advise more productively. At present it's just educated crystal-ball gazing. Given the age of jordano's motorhome and his "like car bulbs" description, it's likely that the present bulbs are ordinary tungsten-filament automotive bulbs. However, such bulbs come in a variety of designs. The Aten Lighting website you've mentioned has a section on LED Bayonet Lamps. Assuming that jordano's current bulbs have bayonet fittings, I'd guess they are BA15S type. Aten Lighting can provide LED replacements for tungsten/halogen bulbs that have a B15 fitting. An example is here (and the webpage also describes fitting variations) http://www.atenlighting.co.uk/caravan-motorhome-lighting/led-bayonet-lamps/18led-b15.html It should be striaghtforward for jordano to identify his bulbs' type. It will immediately be apparent if the bulb has a bayonet fitting and, if that's the case, the fitting's diameter will indicate if it's a 9mm, 15mm or 22mm type. There will be one connecting 'spot' on its base, or two connecting 'spots'. Although an automotive bulb can have offset bayonet 'pins' (eg. combined brake/tail-light bulbs), such bulbs are unlikely to be fitted to motorhome habitation-area lights. So, if jordano's bulbs have a bayonet fitting 15mm in diameter, with a single central 'spot' at the base and with bayonet pins that are not offset, the bulbs are BA15S type. The next step will be to establish the bulbs' wattage and this should be visible on the side of the bayonet fitting. Jordano's bulbs will be 12-volt, but the wattage of a 12V BA15 automotive tungsten-filament bulb can vary from 5W to 21W. Such bulbs used for motorhome interior lighting are likely to be 10W or 15W. Knowing the wattage of the current bulbs will make it easier to decide whether the light-output of an LED replacement will be appropriate. As you say, Aten Lighting also offer 'base adapters' that permit bulbs with a different fitting to be used. A bayonet-fitting adapter is shown here: http://www.atenlighting.co.uk/caravan-motorhome-lighting/lighting-accessories/bayonet-g4-adapter.html If jordano's bulbs are BA15S-type, a BA15S adapter would allow an appropriate LED G4 Tower or Back-pin bulb to be used. http://www.atenlighting.co.uk/caravan-motorhome-lighting/g4-leds.html Whether a single LED replacement bulb, or an adapter + LED G4 bulb, would be the best approach will depend on how much light output is required and (most importantly) what can actually be fitted into the Cheyenne's light-units. The colour (warm-white or cool-white) of the light produced by the LED bulb also needs considering. Link to comment Share on other sites More sharing options...
