John Thornton Posted March 18, 2015 Report Share Posted March 18, 2015 My 1962 TR4 has domed glass instruments but apparently no instrument lights other than for the speedo and rev counter! I have only looked at the oil pressure gauge so far but can't feel any cables to other gauges. Firstly, is this correct? Secondly, I am planning on lighting all instruments with LED - MES lights, is it simply a case of drilling the back of the gauge casings to take claw type bulb holders. Has anyone done this?

Graze Posted March 18, 2015 Report Share Posted March 18, 2015 John My 65 TR4 has lighting to all instruments. I would be surprised if yours never had any lights. I tried LED to the smaller gauges but couldn't get them working - perhaps not enough power. They do work in my TR6. Graze Quote Link to post Share on other sites
peejay4A Posted March 18, 2015 Report Share Posted March 18, 2015 (edited) Autosparks can do a small loom for the instrument lights. It takes wedge base bulbs and I have LEDs in mine. They work fine. Edited March 18, 2015 by peejay4A Quote Link to post Share on other sites
MRG1965 Posted March 18, 2015 Report Share Posted March 18, 2015 Hi I used the 100degree mes led bulbs, work fine on my 64 tr4 small gauges. Mine have the standard push in tubes on the back of the gauges that hold the buld holders. Mark Quote Link to post Share on other sites
TR 2100 Posted March 18, 2015 Report Share Posted March 18, 2015 John, The domed glass gauges fitted to early TR4s do NOT have individual lights. They follow the TR3 style of a ring of clear plastic just inside the chrome ring and are side-lit through this by a pair of bulbs fitted to the dashboard. Trust your overdrive is behaving itself?

peejay4A Posted March 18, 2015 Report Share Posted March 18, 2015 Another nugget of learning there. Quote Link to post Share on other sites
TR 2100 Posted March 18, 2015 Report Share Posted March 18, 2015 Another nugget of learning there. Maybe. (if you mean my post) Just waiting for Stuart to correct me. AlanR Quote Link to post Share on other sites
RogerH Posted March 18, 2015 Report Share Posted March 18, 2015 I have a March 1962 TR4 and the lights are as you state Alan - side illuminated from two bulbs attached to the back of the dash Roger Quote Link to post Share on other sites
John Thornton Posted March 19, 2015 Author Report Share Posted March 19, 2015 Thanks for all of the information, it looks as if the gauges are as Alan and Roger say so I will take the dash off (wooden) and investigate further. Quote Link to post Share on other sites
peejay4A Posted March 19, 2015 Report Share Posted March 19, 2015 Maybe. (if you mean my post) Just waiting for Stuart to correct me. AlanR That's precisely what I meant Alan. I had a '64 TR4 with domed instruments in 1973 but I didn't do an iota of work on it so never got to understand niceties like this. Quote Link to post Share on other sites
stuart Posted March 19, 2015 Report Share Posted March 19, 2015 Maybe. (if you mean my post) Just waiting for Stuart to correct me. AlanR You are correct Alan, I believe they changed them when the later flat glass instruments came in. Stuart. Quote Link to post Share on other sites
