Since most of us drive over 30, how about an "over 80 lamp'? LOL

Re: 30 light
I got 6 replies of people who claimed to have been over 80 in a TC. I don't doubt them , of course. I was just suggesting,,,,at thirty it would stay on the whole time on an interstate or throughway.

Re: 30 light
I've been 78 in my TC, If I get much older I may have trouble getting in or out of the thing.

Re: 30 light
I just barely reached 80 in my TC at Bonneville with the tach reading higher than I was comfortable with, considering how far from home I was and especially how far off the highway!

Re: 30 light
hi Paul - count me in and make that 7 Actually 80 in a "bog standard" TC
would be difficult but theoretically posssible with a good engine - with an
8/41 diff. the gearing is 15.84mph/1000rpm and maximum power is developed at
5,200rpm = 82mph.
An 8/39 gives 16.65mph/1000rpm so 86.6mph @ 5,200rpm and an 8/37 gives
17.55mph/1000rpm so 91.3mph @ 5,200rpm.
I currently run an 8/39 (the 8/37 is a little too high for towing a trailer)
and occasionally push it to 5000rpm which is 83mph. But after 12 years of
running with no air filters (no room with the TF carbs) the poor old XPAG is
getting a little smokey, so I usually restrict things to 4000rpm (66.6mph)
which it will happily do all day. TC0978 could certainly do with a "30"
light, because the other week I got stopped by a very nice young WPC for
breaking the limit. My excuse that the speedo is out of sight under the
tonneau did not cut much ice...

30 light
Attachments :See below for an article that I wrote a while back. [b][i]Doug Pelton[/i][/b]FROM THE FRAME UP, LLC[u]www.FromTheFrameUp.com[/u]480-588-8185 [b]Please note: [/b]For fastest service for orders, email to: [u]order@FromTheFrameUp.com[/u] [b]Shedding Some Light on the MG TC Map & 30 Lights[/b] In 1935, Howard Hughes set the world speed record of 352 mph in his Hughes H-1 Racer. That same year England passed legislation for the first time to limit the speed to 30 mph in all towns and villages. This very act set the stage for the infamous 30 light in our cars today. But not all TC’s had one. Only the Home Models had the 30 Light on the dash and the particular components associated with 30 light in the speedo. Or is this correct? Well, no, not completely. Let me explain. The TC has 2 panel lights, one on each side of the center control panel. On an Export Model these are both maps lights. However, on the Home Model, the right hand map light was originally a 30 light. Its function was simple, come on and alert the driver if the speed reached 30 mph. Both the map light and the 30 light use the same the same base. So this is a common item and interchangeable between the 2 lights. The difference however, is in the trim caps. The map light has a window to shine the light out of and “onto the map”. The 30 light is totally enclosed except it has a beveled edge green lens in the end of the cap. But how does the 30 light work? Inside the TC speedo there is a mechanism that simply acts as an on/off switch. At 30 mph a contact is closed and grounds the circuit. Here is the interesting part. All TCs came with this switching mechanism inside their speedo. It is integral to the speedo itself and there was no such thing as a Home or Export Model speedo. If you look at the back of an original speedo you will see the small finger screw cap that is used for wiring the 30 light circuit to. That’s it. Just connect the wire to this terminal. The instrument is grounded by the speedo cable going to the gearbox which is grounded to the chassis to complete the circuit. If you look at the photo of the inner workings of the speedo you can see the center post for the needle. Below that is a disc that makes contact with the brass bar when the speed reaches 30 mph. So what if your 30 light does not work? [img]cid:image005.jpg@01CEC8B5.0A23B0B0[/img][img]cid:image006.jpg@01CEC8B5.0A23B0B0[/img] Remember the bases for the 2 lights are the same. Check to see if your base is turned on. Like your map light, turn the base of the 30 lamp clockwise to the on position and leave it there all the time. If this does not work replace the bulb. If this fails then you will have to get into wiring and maybe even have your speedo checked. For those of you, who will be rebuilding your dash, please reference the TC Instruction Manual (Brown Book) for proper wiring. However, for the early TC owners, keep in mind that the current reprint of the 1945/48 Home model wiring does not show a 30 light. You will have to use the 1948/49 Home model diagram. Or visit http://fromtheframeup.com and look under Tech Tips for a copy of the original 1946 wiring diagram with the RF91 regulator with the early color codes for wiring. Acknowledgements go to Fred Kuntz and Craig Seabrook, Whitworth Shop, Ohio for their technical assistance and photos. If you are in need of a Map Light or 30 Light, these are available with many other hard to find parts from “From the Frame Up”. As always send comment to doug@FromTheFrameUp.com

Both "From the frame up" and "Abingdon spares" list the 30 light cover with lens.
