VCCA Home Forums TECHNICAL - GENERAL Electrical - 6 volt Tail Light Sockets

Hi All, I'll be putting in the turn signals come spring. But I'll be needing the duel contact pads for, inside the tail light sockets wont I? Will those bulbs be #1154's? Thanks for any help on this,

The double filament bulb with two contacts on the back and two filaments in an 1154, same as what was used from 1939 and up. It was wo bulbs in one and the only bulb used in those tail lights.
Your 1937 lamp as tow bulbs. The tail light bulb can continue to be the tail light bulb-period. The larger brighter bulb is the stop light bulb. This will now be the stop light and directional light bulb......when the proper switch is used.
I would recommend using a 21 candle power 1129 bulb for the stop lights (same candle power as an 1129) and a little socket repositioning may be necessary for the bulb to fit in the lamp. The original 15 CP bulb is way too dim.
Also would replace the original #63 3 CP tail light bulb with a 6 CP bulb.
In other words an 1154 is not used.

PS-will get at checking out the fogs this week end. Had a few unexpected things come up this week.

You can convert your '37 housing to accept the 1154. Go here and scroll down about half way to part number C7002X. I converted my 38 using this. Since the 1154 tail light filament is 3cp (stop is 30cp) I also am using the Hirsch halogen bulb which is significantly brighter.

The disadvantage of using an 1154 the tail light filament is only 3 candle power. With the lens in place on a 1937 the tail light will be about as bright as a candle.

Thanks Gene & Tiny for the replys. So what your telling me Gene, is that I can still use the single contact bulbs{With the turn signals} but, to change the cp on the brake light bulb? Now, as best as I can tell, my generator and voltage regulator are from the early 50's. Tiny, Could I use halogen bulbs with this set up, or do I have to put on an alternator with these bulbs? Also thanks for the heads up on this site about the conversions. Thanks,

The 1940 and up generator/voltage regulator cobination will take care of the halogen bulbs....just hope the wires are up to the task.

Gene, where can I get these brighter bulbs, {1129's}? I ran all new wires using 14 gauge. I went out and took a look at my generator. Now, it has some damage to the tag, but here are the numbers I got off it, 102 49 om7. Gene, maybe you can make some sense of these numbers. The voltage regulator is on the firewall. It has the three contacts along the bottom and its a Delco Remy. It was on the car when I bought it, and was told it is from a early 50's Chevy. How true this is, I don't know. Any help on this would be appreciated. Thanks, Joe.

Hey Gene, maybe I'm reading this wrong but isn't there some thing wrong with these numbers? "I would recommend using a 21-candle power 1129 bulb for the stoplights (same candle power as an 1129)"
And do you know of anywhere there is a chart like we used to have around the parts room with the bulb data on it. At one time I had a chart with the bulb profile, voltage, amperage, wattage and candle power but I haven't seen it in years.
DG

I have one of these charts handy. Chevgene recommended switching the #63 bulb (3cp) to a 6 cp bulb which according to my chart would be a #81.
The candlepower for the 1154 is listed as 21cp and 3cp.
If anyone wants to know voltage or cp of any other bulbs, just ask.

Trying to figure out your generator number.I have lists of all the numbers. Can you type in from the beginning what you have and then leave the correct number of spaces where numbers are missing.Thanks

I don't know where I got 30 cp for the 1154. I double checked and you are correct at 21. Geeze I hate it when I prove my humanity (to error is human).

Hey Guy's, Thanks for helping me out, on all these bulbs an candle powers.But can I use any of these in my stock sockets when I put in my turn signals? Or do I have to change to double contacts on the bulbs and sockets? About the numbers on my generator. Their is one number rubbed out on the tag. But here it is, 102?49-0m7. The question mark, is the number that's rubbed out. This has been on the car since Ive had it, and has worked just fine.Thanks,

If you use the mentioned #63, 81, 1129 bulbs you can use your original single contact sockets. The 1154 bulb will neeed a double contact socket.
If I had a 1937-38 car I would look into the LED tail light adapter. The LED is brighter and consumes very little power.
My personal experiance with the halogen bulbs was not good unless you like buying new bulbs evey year and/or like to see your wires smoking.

I bought THESE LEDs and it was a waste of money. Six volt LEDs are not much brighter than the incandescent bulbs.

I have heard the same thing from other dudes as well. Don't waste your money!

WOW, thanks for all the info guys. After all that, I think I'll stay with the Ole "tried and true" type bulbs. After my wife suggested using a magnifying glass to see the numbers on the generator, I went out and looked agin. Here's what I got,1102749. Can anybody please tell me the year on this? Thanks,

This number is equivalent in my book to the generator for a 1949-1952 Chevrolet, the original generator for 49-52 Chevrolet being 1102667.

More detailed in another book I have. 1102749-Late 1951 Chevrolet and early 1952 Chevrolet, and same for Chevrolet trucks.Hope this helps.

Hey Neil, Thanks so much for looking up the info on this for me. But I wonder what the 0m7 means? I knew it didn't have the original generator to start with, but it worked just fine. So thanks agin Neil, Joe.

Ok guy's, here's another one. Where am I going to find #1129 bulbs? Looked in the FS and Chevys. No one has them. Anyone know where I can get some? or have they gone the way of the Dinosaurs! Thanks,

Thanks Gene, Sometimes I can't see the forest for the trees I guess.

Your FLAPS should be able to order them if they don't have them in stock. I get my 6v bulbs from the local Bumper To Bumper store. If they don't stock them I have to buy a box of ten but that's OK. Then I have extras on hand and don't have to pay shipping.
