How many of you have mounted an Overdrive Indicator Light and where did you mount it? Color of light? Pictures please.

I was thinking of it but left it for now. I was going to put a round green light in one of the blanking plates for rocker switches below the radio. I'd be curious to see some pictures as well.

It is possible to mount one in the center console next to the Hazzard Light. This hole is supposed to be for a white MGBGT heated rear glass indicator light. IMHO the way to go is to use one of these lights on a roadster as an OD indicator. I'll get to it when I next hit the boneyard as I know there is one here in DFW.

Another option is to use the "Fasten Seat Belts" light just below it. Your car should still have the lens and socket, otherwise it is a common part.

I bought some LED's to do this, but haven't executed yet.
My opinion is that Yellow is an appropriate colour given the circuit wiring. smiling smiley

I have an amber light installed in the center console next to the red hazard light, but not yet wired in to the O/D yellow wire circuit. I am using the "Seat Belt" light position as a fog lamp indicator but I have replaced with a later-model green "Beam" light. (Sorry - no pix available from my work location)

I used an amber light mounted in the center console. However, I soon got annoyed with it because it was on all the time the car was in overdrive so I got to thinking! A little research and I eventually came up with a circuit that monitors the O/D switches so that the light ONLY comes on if the inhibit switch is open (in a non-O/D gear), but the O/D switch is closed. AND if the light is on, and you shift back to an O/D gear, the O/D will not engage until you cycle the switch off and on again!

The original version was a little temperamental and was temperature sensitive - so I redesigned it to make it operate more consistently and after a few tries, got it working. It is now reliable - and for sale! (Shameless plug). It really is a LOT better than having that amber light on all the time - especially at night!

Go to my website if you are interested - see below!

Since my overdrive will engage in any gear (including reverse)(long story) and I have not damaged it yet......!!! I did the simplest thing I could think of and it took about 15 minutes. I removed the steering column shroud and tapped into the overdrive switch (white wire as I recall). I ran that wire over to the brake warning light which was not in use as the actual switch on the brake line was broken. Works great and it never fails to catch my attention even in the brightest light.

Wray told me how to wire into the "Fasten Seatbelts" light which my father-in-law had disconnected with the buzzer. I'd thought of it as a memory aid to remind me if OD was in or out while driving.

One afternoon I was about to back out of a mall parking space & happened to glance down to see the light lit. I guess I'd touched the lever while parking & was glad of the light as the B was in reverse & I was using the clutch. I've read here that reverse will damage the OD so don't want to find out as that would be an expensive repair & I'd regret having to go back to just direct drive.

I'd recommend a warning light somewhere! THANKS Wray!

Cheers

Right next to the switch. This is an original Rootes accessory from the 60's.

I copied this picture from a MGE member (sorry I can't find his name) and made one up for myself and put it where seat belt light was.

I installed an OD light from a 1973 Volvo 1800ES. Couldn't be happier with how it works and looks.

Was on my list to do as well.
