I am thinking about changing my dashboard bulbs (speedo, tack & gauges) to LED. Can anyone give me some input on this?

You might try a search, the subject has been covered.

The complication is that you need to replace the dimmer switch, as the LED cannot be dimed by the original dimmer.

You'll find other sources by doing a Topic search, but Moss has interior LED dash bulbs as well as some exterior in their catalogs.

The bulbs you need have an E10 screw base, if you are not in a hurry you can get the same bulbs Moss sell diresct from China at about 1/10 the price with free shipping on ebay.

Sometimes the heat fom our old incandescent bulbs can burn out the Green plastic shield inside the instrument. But you can get Green (or other colour) LED's to correct this.

Possible options: I don't know what year TR6 you have but I have a '76 that I converted to all LEDs. I purchased my bulbs from Classic Car LEDs (www.classiccarleds.co.uk), Bristol, UK. They have a kit specifically for the TR6 gauges in white, warm white, green, blue or red. Also included are a blue main beam indicator bulb and green turn signal indicator bulb. No bulb is included for the ignition warning as they do not recommend replacing this bulb with an LED. They have the E10 screw fitting. Bulbs can also be purchased individually. Having said all of this, I did not replace my gauge bulbs with these bulbs (all others I did!) but had my gauge bulbs replaced with LED light strips by Morris Mintz at West Valley Instrument Specialists in Reseda, CA. I like them a lot. I had West Valley restore my gauges and decided to have them add the strips. The cost was $350.00 just for the LED strip installation. Expensive for me, but I do like them and am glad I chose to go with them. I realize there are many less expensive options as indicated in above responses. As far as the dimmer rheostat is concerned, you don't need to replace it under certain circumstances. I am not familiar with any possible differences in rheostats from different years. In March of 2017 I sent my original operational rheostat to Dale Osterndorf (od_cntl@hotmail.com), Roanoke, VA for conversion to solid state for use with the LED's. This is what Dale indicated to me: " Assuming it's original, it should be in good mechanical condition (the threads are susceptible to damage and difficult to repair). The converted dimmer should not cause any flicker with the LEDs, so nothing special you need to do for that." The cost at that time was $47 + $7 shipping to Wisconsin. His turn around time was 3-4 weeks at that time. My rheostat is installed and works perfectly with no flickering etc. He's very good to work with and I suggest you contact him with any questions regarding your rheostat and its suitability for conversion, if you're interested. There are many options out there...these are the ones I chose. Hope this info. helps in some way! Happy cruising!

Moss has a decent
video on changing to LEDs. I believe the TR6 turn signal indicator (at least my 71) falls into the category of needing ballast resistors.

To dim the dash LED's you need to exchange the stock Rheostat with a PWM

LED's can be used to replace the turn signal bulbs if an electronic two pin flasher module (from your FLAPS) replaces the standard electromechanical unit.

Hi Tony,

Does that hold true if the bulbs in the exterior lights are converted to LEDs? What do you mean by FLAPS?

My understanding from watching that Moss videos says that the LEDs in the exterior bulbs are so efficient they don't produce enough draw to create a ground when the opposite side is open on the turn signal switch. Am I understanding that correctly?

Thanks, Allan

I replaced all the outside lights (except head lights) with LED's off ebay. For the turn signals I needed to either add resistors (which seemed a little complex, and in any case, my aim was to reduce current draw ) Or just buy a new stanard, 2 pin, $8, electronic flasher unit from Canadian Tire.

Lights have been great on two cars for two years now.

I also went with Classic Car LEDs. I have not yet replaced the dimmer. This is what they look like. You can even see the High Beam, Trafficator and Oil light in the daylight. I went with the green option.

Thanks Tony, Tim, and Doug.

Tim, that setup looks great. Where did you get the dashboard from?

In Doug's journal he makes the point that the LED's must not ground on the instruments, the ground wire goes back to the PWM controller. I had forgotten this.

It is quite likely that if you fit LED's you might feel the need to dim them. Whereas with the stock bulbs, you need all the light you can get.

Tony,
Do you have a link to the Ebay bulbs?

For dashboard or outside lights.

Whichever there are so many options. The instrument lights are E10 base 12v. Outside lights are 1157 and 1156 (one is a twin filiment bulb for brake and side light)
