Markymark Posted April 29, 2018 Share Posted April 29, 2018 Pushed the boat out and bought a CSR clock for my SV. Has LED backlights I think making the rest of the dials look very dim. Bought some new brighter lights for the small gauges. Easy to replace these. The Speedo and tacho look like the case needs to be removed. Has any body done this and any words of wisdom/advice as I dont want a disassemble them and b****r them up? anybody got a heasds upp on it?

Member Jonathan Kay Posted April 29, 2018 Member Share Posted April 29, 2018 IIRC this varies between instruments. Have you had a look at the back and could you add photos?Previous discussions: 1, 2 with some photos and links to instructions. And the full search.Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted April 30, 2018 Author Share Posted April 30, 2018 Thanks Jonathan! Will limber up and stretch to get my torso under the dashboard! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 1, 2018 Member Share Posted May 1, 2018 :-)But I'd try releasing them by feel. More obstetric than speleological.Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 1, 2018 Author Share Posted May 1, 2018 Yup good thought - Tried to get phots but retaining bars cover the serial numbers so going to have to take off the wheel ( as I have a motolita type) the 7 is a 2010 150 SV. Link to comment Share on other sites More sharing options...
Markymark Posted May 3, 2018 Author Share Posted May 3, 2018 Jonathan,The instruments seem to be the ones fitted after 2005 - the speedo matches the picture you put on an earlier post,see below. Tacho I guess is similar see picture below.Do you have an idea of what bulbs these use (286 ?) as I would like to get some brighter ones.thanks for any inputMark Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 3, 2018 Member Share Posted May 3, 2018 I think I got the types wrong in this recent discussion.Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 9, 2018 Author Share Posted May 9, 2018 JohnathanI looked at the bulb in the tacho and the pictures below are the bulbulbs.Caerbont said they were wedge T15 but they dont look like it to me! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 12, 2018 Member Share Posted May 12, 2018 Does that lamp come out of the green bit?Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 14, 2018 Author Share Posted May 14, 2018 HiI,ve given it a gentle tug but it does not come out. Reluctant to use force as I could break it and don't have a replacement. Emailed Caebont to ask them about replacements. Will post on here to share any words of wisdom.BRM Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 14, 2018 Member Share Posted May 14, 2018 In *that case I think it's this type of 286. Does that look right?Jonathan* ;-) Link to comment Share on other sites More sharing options...
Markymark Posted May 14, 2018 Author Share Posted May 14, 2018 Hi Jonathan Yup this looks right! Caerbont told me this."The Caterham speedo and tacho (and others) are fitted with a 2 Watt bulb and we don’t have any higher output alternatives. However, I am informed that an LED alternative is available on Ebay and others. You need to search for a wedge base T1.1/2, 5mm,the lamp and holder are two separate parts.

Member Jonathan Kay Posted May 14, 2018 Member Share Posted May 14, 2018 Is the above from your car or have you sourced it?Click the link! It was just a convenient image for identification. :-) Yes, LEDs are available. But NB: If you are changing one lamp most of us prefer others that are similar to be the same. If you change the alternator/ ignition warning lamp from an incandescant lamp to an LED you'll probably need to add a resistor. It has been said that the loss of heating by the incandescant lamp can make misting in the instrument more likely.Auto Bulbs Direct were good when LEDs were starting to appear, but I'd now check if Just Add Lightness offer them. Then there's that website in Bristol that some Members like...Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 14, 2018 Author Share Posted May 14, 2018 Thanks Jonathan missed the link as I did not first look at the post on the web but the message on my phone!Thanks for the other advice. I dont have an ignition indicator just indicator and main beam. looks like these are a return to factory if they go. Heard about the misting- get some on my car now but I am not to bothered by this.

Member Jonathan Kay Posted May 27, 2018 Member Share Posted May 27, 2018 Solved?Jonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 29, 2018 Author Share Posted May 29, 2018 JonathanI have just managed to put together a solution. Caerbont very kindly send me three black carriers that I guess they use now. To which I added the LEDs from Classic Car LEDs ref 286 T5 Dashboard LED Upgrade Bullbs. See pics below and also the end result !Duncan was very helpful anat Classic car LEDs and my orders arrived the next day/ ( I ordered some rear light LEDs as well and a rear reversing light in brighter LED form) great improvement in visibility. Cant comment on the reversing light as during the swap over I noticed it was not working. Traditional and LED bulb were working. Will check the fuse first then maybe back up here to see where to check the earth and then maybe the switch itself. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 29, 2018 Member Share Posted May 29, 2018 Gauge brightness looks consistent... did you change the full beam warning light, and how bright is that?ThanksJonathan Link to comment Share on other sites More sharing options...
Markymark Posted May 29, 2018 Author Share Posted May 29, 2018 JOn the Tacho there are three "warning lights. The centre blue for the main beam and left and right for the indicators. These are not as far as I can see accessible from the rear of the gauge - ak removing the rubber bung shown on earlier pictures. The good news is that with this new set up these indicators are perhaps up to 30% brighter (my perception only) - perhaps as the LEDs draw less current there is more for these indicator lights.
