Howard Posted June 12, 2016 Share Posted June 12, 2016 I am planning to swap the feeble side lights on the TR7 for LED's with the intent of improving the visibility, particularly from the front before the RBRR. Has anyone tried this on their car?The TR7 & equivalent bulbs appear to be as listed below:- Qty Triumph Ref. Lucas Ref. LED equivalent (to be confirmed)Flashers / Stop 6 382 / 21 W SCC BAU 15s - P21W 382 Twenty20 LED 12V P21W Bayonet Bulb £12.50 (Ea)Tail 2 207 / 5 W SCC BA15s - R5W 207 Ring Premium LED 12V R5W Bayonet Bulbs (Pair) £14.99Front 2 GLB 989 (?)

Harveyzone Posted June 12, 2016 Share Posted June 12, 2016 Quoted from Spitfire6 You well need a 2 or 3 terminal LED flasher unit, cheap of EBay. I have a 2 terminal one and I need to add a left and right telltail light to my dash and then I can junk the front bulbs and fit LED's. Blimey, i hadn't realised that you need a special flasher unit for LEDs! Why's that? I hadn't really thought about how they worked but I (perhaps naively) assumed that they were just some kind of on/off switch/relay that passed 12v alternating to 0v!I have started down the LED route, but only done instrument panel and side lights so far.

Harveyzone Posted June 12, 2016 Share Posted June 12, 2016 Quoted from Spitfire6 Hi, The old electro-mechanical ones work via current. The LED's will not draw enough current to allow them to cycle.The solid-state modern ones will cycle incandescent bulbs as well if they are rated to >44 watts. Ah - that makes sense. Thanks for clarifying. Good job I hadn't got to my indicators yet Quote Link to comment Share on other sites More sharing options...
Toledo Man Posted June 13, 2016 Share Posted June 13, 2016 Beware of using the bright white bulbs. Through coloured filters they look a bit washed out. To get round this you can either use coloured LEDs or warm white ones. I've got coloured tail/brake lights and whar white sildelights in LED on the Dolomite.

Howard Posted June 13, 2016 Author Share Posted June 13, 2016 Quoted from Spitfire6 Hi,PS. you will need a hazard flasher LED unit as well unless you modify your hazard switch to work with the single flasher unit. Iain, Thanks - the indicator was changed to an electronic unit some years ago, but had totally forgotten about the Hazard Flasher needing to be changed as well.Quoted from Toledo Man Beware of using the bright white bulbs.

Toledo Man Posted June 13, 2016 Share Posted June 13, 2016 I was supposed to put "warm white" in my post.Be careful of ebay. There are some poor quality LED bulbs out there even from the UK suppliers. I bought a pair of sidelight LED bulbs for the Astra and they only lasted 8 months. I bought some decent quality one which are still going strong to this day. I compiled a lightbulb guide for the Dolomite on the TDC forum which was for lightbulbs in general but is useful for ordering LED bulbs.

Howard Posted June 13, 2016 Author Share Posted June 13, 2016 I am thinking of getting them from http://www.superbrightleds.com - its a US supplier, but they even include Triumph cars in their options and recommendations. They also have all the technical info to back up the selection, which is better than most of the other sites.Living in Qatar I have a US address courtesy of a courier company and there is no/minimal duty payable here so intentional shipping is not an issue. I will then bring them back to the UK with me.CheersHoward Quote Link to comment Share on other sites More sharing options...
Howard Posted June 20, 2016 Author Share Posted June 20, 2016 One complete set of bulbs ordered with a 20% discount yesterday Just have to organise the replacement hazard flasher before the RBRR. Quote Link to comment Share on other sites More sharing options...
AlanChatterton Posted June 20, 2016 Share Posted June 20, 2016 I have an original 2 pin flasher unit in mine, so If I want to upgrade to LED (and to help with towing) a modern solid state 3 pin flasher unit is needed. (two, one for indicators and one for hazards)I seem to recall somewhere that the 3rd pin you need to put to earth........... but can anyone point me in the right direction of the correct flasher unit and which pin to earth, or is it obvious when you get it?Thanks Quote Link to comment Share on other sites More sharing options...
Howard Posted June 20, 2016 Author Share Posted June 20, 2016 Most of the usual suppliers should be able to provide them, but Robsport fitted mine as the flashers on TR7 are notorious for going very slowly due to earth problems. You are correct that the third terminal needs to be earthedCheersHoward Quote Link to comment Share on other sites More sharing options...
Toledo Man Posted July 1, 2016 Share Posted July 1, 2016 Some cars have separate flasher units for the indicators and hazards. That is certainly true of my Dolomite. I have fitted a modern indicator one on mine and it has 3 wires one of which is for the earth. Quote Link to comment Share on other sites More sharing options...
