MG TD TF 1500 - Halogen bulbs need relay?
I did a search and found nothing definitive on whether or not I can fit rear halogen bulbs for the brake/rear lights. Does this upgrade require a relay or some other nefarious electrical work?
Thanks again as always! This board is great!
Modern lights need modern wiring. If you're still using the original wiring harness, you're taking a risk by running a high current device on this old harness. I wouldn't do it.
A few years ago, I replaced my headlamps with the Sylvania Silver Star sealed beams. Great lamps, but I'm sure I'm pushing the wiring to its limit.
Have a gander at Bud Kruger's web-site "T-Talk" - http://www.ttalk.info/Tech/TechIndex.html.
I'm sure you'll find what you need in there to re-wire for high current devices.

|Dave - Before converting to the halagon bulbs, look at the power consumed by each filiment as compared to the original bulbs. Some of the halagon bulbs use a considerable amount of power while others don't use any more than the original bulbs. I would suggest putting a relay/arc suppression circuit in the brake light circuit regardles of which bulb you use, to insure that the brake light switch does not start giving you problems. For a relay/arc suppression circuit that you can make and install, see my article at: http://www.omgtr.ca/technical/brakelightrelay/brakelightrelay.htm|
Gord - You can reas easy about the Sylvania Silver Star sealed beams, I checked the current draw on them before sticking a set in our MGB and found that they draw the same amount of current as standard sealed beam head lights. Cheers - Dave
|hello, for the tail light/brake lights have you considered LED'S ? regards, tom|
I think Dave is talking about brake lights. My car has them, I believe, with the original wiring (no relays) and they work fine and are very bright. My car also has them with the front side lights, which are also great. I think they draw much less power than headlamps.
Regarding halogen headlamps, I bought them from Moss, turned out to be wagner/sylvania and they draw the same current as the original bulbs (roughly) I am using them with the original wiring loom (getting old and cracked) and so far have had no problems.
|Tom Peterson, where did you find LED's that work with the MG ground system? I have been searching for LED 1157s but they do not work with the original grounding of the car. Something about the current in an led bulb.|
|One of the TC owners in our club had someone 'make up' positive ground leds....sounds like it is something an electronic shop (?) can do?|
Also found them with a search on the web...forget now where they showed up.

|For those with negative ground systems, go here for LED 1157s. I have bought bulbs from them before, but not their LEDs.|
|hello tom, i will post the LED info. it will take me a bit to dig it up. regards, tom|
