Quack Posted January 30, 2022 Report Share Posted January 30, 2022 Does anyone know the best way to go about this? Can i swap the bulbs out for halogens or is that only possible with the headlamps? Link to comment Share on other sites More sharing options...
Badwolf Posted January 30, 2022 Report Share Posted January 30, 2022 Does the Herald have the same night dimming relay as the Spitfire? If so, disconnect the earth lead from it (I think) Link to comment Share on other sites More sharing options...
Quack Posted January 30, 2022 Author Report Share Posted January 30, 2022 Hmmm I don’t think so, atleast I’ve never come across one anywhere in the car. Link to comment Share on other sites More sharing options...
PeteH Posted January 30, 2022 Report Share Posted January 30, 2022 Mine (13/60) look like standard 21W Bulbs to my Eye?. If so the issue is likely to be Bad Earthing? Reducing the "seen" voltage at the lamp, rather than anything else, Cleaning the lens and or reflectors might help?. Colin reported better lights after he did a service on his. Ultimately a change to LED`s? Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 30, 2022 Report Share Posted January 30, 2022 there is no dimming relay on Heralds you can fit LED indicator and side lights but will have to change the flasher unit for a LED compatible unit headlamps bulbs can be changed for halogens but if they are sealed beam lamp units you have to replace the whole headlamp to a bulbed fitting unit first job is to confirm you have the correct running voltage of around 14,5V voltage drop to lamps in the bonnet are very prone to poor earthing and many add relays to get 14v to the front not the often only around 10v due to poor switches long wire runs and bad earths the basics have to be ok to start with before you mess with supposed upgrades.

trigolf Posted January 30, 2022 Report Share Posted January 30, 2022 Heraids were never fitted with a night dimming relay. You can get led indicator bulbs, but you normally have to swap the flasher unit for an led compatible item otherwise they won't flash properly.

NonMember Posted January 30, 2022 Report Share Posted January 30, 2022 As the others have said, the most important thing for getting the indicators to adequate brightness is to fix the faults, not invent new. Your wiring is old and probably not as clean as it might be. The earth connections are terrible. The bulb sockets probably have a layer of corrosion on them and the crimps on the wires may not be any good now. There's no point sticking a multimeter on it, by the way. You'll do so and see a resistance of an ohm or so and think "that's about zero" because the multimeter isn't very accurate around there. One ohm is decidedly NOT "about zero" for indicators. Two ohms will stop them working altogether. I had that on my Toledo - a corroded terminal on the light unit. Link to comment Share on other sites More sharing options...
Chris A Posted January 30, 2022 Report Share Posted January 30, 2022 I suppose a good way to determine if they have lost brightness would be to compare then to a modern that still uses bulbs not LEDs? The ones on my 13/60 seem ok by, from memory of the distant past, the standards of the late 60s early 70s. I think I'll do a comparison at some point soon. Too late today, been out for a drive in the sun now need to get on with boring stuff. I have fitted LED stop/brake lights though and they did improve things.

Can you get led with the correct fittings and do you need any other widgets. I'm also thinking of installing a rear window mounted stop/turn led strip, can you get them with "Stop you B*ast**d" letters? Iain Link to comment Share on other sites More sharing options...
Chris A Posted January 30, 2022 Report Share Posted January 30, 2022 59 minutes ago, Iain T said: Chris, what did you change? Just the bulbs, straight swap. While the kettle was boiling for our afternoon cuppa, I'm drinks monitor here, I popped out and compared the modern and Triumph indicators. The Triumph's are slightly yellower but just as visible as the Yeti. So I would agree with other comments, first make sure you are getting full power to the bulbs before getting the wallet out. 1 Link to comment Share on other sites More sharing options...
Quack Posted January 30, 2022 Author Report Share Posted January 30, 2022 Cheers for doing that Chris, yep looks like it just must be the old wiring so I’ll be getting to work on that. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 30, 2022 Report Share Posted January 30, 2022 and the front side/flasher relies on a self tapper or screw to the body for the earth , often hidden corrosion here you may be lucky some lamp units do have a separate earth but they are again hidden in the bonnet with the same degraded contacts along with the bonnet earth link in the harness a new wire bonding the earth from the lighting back to the battery earth is a good idea ontop of adding full battery power via a relay supply at a later stage of working on an improvement every little helps turn glow worms into something illuminating Pete Link to comment Share on other sites More sharing options...
Steve P Posted January 30, 2022 Report Share Posted January 30, 2022 I fitted rear LED bulbs to my MK 1 Vitesse a few months ago, side, brake and number plate lights much improved but when indicating right, the stop and tail light flashed. It turned out to be the rubbish earth on the over rider bolt, cleaned that up and it works fine. Front indicators still filament bulbs.

Iain T Posted January 30, 2022 Report Share Posted January 30, 2022 Paul, where did you get your led strip? Been on Classic LED website for stop/tail and front sides, for the minimal cost and increased safety a no brainer! Iain Link to comment Share on other sites More sharing options...
Wagger Posted January 30, 2022 Report Share Posted January 30, 2022 I fitted 2 watt bayonet LED's to my front parking lights a while back, They are bright enough for daytime running lamps. Might get flashed at night as they could be annoying for oncoming drivers. Should have bought 0.5 watt versions. Personnally, I do not like following cars with LED brake and indicator lamps. Sudden 'Turn on' leaves an inprint on my retinas. No time to look away. My brothers were 9 years old at the end of WW2. They were used to really feeble vehicle lights. Dispatch riders wore goggles with slots cut vertically, horizontally and at 30 degrees to the horizontal. My mate still has his uncles. Fabulous, they don't mist up and make you look like a Dan Dare adversary. In my house, since fitting LED bulbs in the hall and stairwell, the switches are failing because breaking the current is not burning the oxide off the contacts. Can't win. I leave them 'ON' now so that burglars can see when we are not in. Picture on the door of the dog with a dripping leg of meat in his jaws has worked so far.

Absolutely, err, brilliant. Recommend them to anybody. I also have a pair or small red led "eagle eye" buttons fitted to the rollbar on my spit, a bar wouldn't work. But like the extra high level brake lights too, about the same height as some modern stuff.... 1 Link to comment Share on other sites More sharing options...
PeteH Posted January 30, 2022 Report Share Posted January 30, 2022 I`ve been on the lookout for the running flashing strip lights. (For high level, on my Camper). Not available in the UK except for specific vehicles. However you can get them from China or the USA?. Pete Link to comment Share on other sites More sharing options...

Paulfc Posted October 13, 2022 Report Share Posted October 13, 2022 Hi, Came across this topic while browsing. Just cleaned and polished the reflectors, washed the glass and wiped the bulb on the rear cluster of my TR6. The improvement is “eye catching” . However, the front side lights not so impressive so will be installing LEDs back and front and will use them, for my own added safety and that of other road users, as daytime running lights.

Peter Truman Posted October 13, 2022 Report Share Posted October 13, 2022 If using LED's on Flashers you may have to upgrade to an electronic Flasher Can as LED's might not have enough load to make the old Bi-Metalic Flasher Can work. How do I know? Link to comment Share on other sites More sharing options...
HowardB Posted October 13, 2022 Report Share Posted October 13, 2022 You can avoid changing the flashers by installing a 6.8 Ohm 50 W resistor in parallel with the LED bulbs. RS Components can supply them https://uk.rs-online.com/web/p/chassis-mount-resistors/0160922 . This does work and until I get round to sorting out the wiring on my TR7 V8 conversion & refitting the electronic flashers I am running with a resistor between each of the rear indicator lights & earth.
