Guide 682C Headlights

[timkins]

I recently purchased a pair of Guide 682C Headlights and I am in the process of preparing them for use. They need to be rewired which I am doing BUT the small light used as a parking light needs to be replaced. What is the best method to replace this socket without ruining the bucket?

Are you changing them for a bigger socket, or because of damage?

[timkins]

I would like to make it a dual signal parking/turn signal

Disregard the previous post. A little gentle tapping on the socket and it popped right out. The more I think about it, the more I am inclined to just leave it alone and find someplace else for a turn signal.

They make a very bright LED bulb that fits that socket. Back about a year ago on this site I showed how to use a resistor and a couple diodes to use one bulb to get both turn signals and parking lights out of a single filament bulb. There is a drawing here

He is running 4 bulbs, but don't let that confuse you. If you have a radio shack nearby it's under $10 to do both sides.

Thank you for the reply and link but sadly all of the Radio Shacks in this area have closed. I will probably just try a couple of the local suppliers for the parts I need to complete this. Again Thank you!

You can also get the parts from Amazon but you have to buy larger quantities. Newark Electronics also has them. I bought the bulbs from Amazon.

Same thing happened her a couple years ago. We were in the most local RS when others were closing. Guy said that they were the largest and busiest, so they were staying open. Closed by the end of that year.

I received a mail order from Radio Shack yesterday. I needed some resistors. It was way more than if the local store would have been here, but way cheaper than driving 30 miles to my nearest electronics store. My resistors were about a buck and $4 for shipping. Driving to get them would have been 4 gal of fuel and a couple of hours. Mail order was 3 or 4 days.

I have looked at the link that was sent and it confused me. Would taking the 1 wire from the turn signal and the 1 wire from the  parking light  and attaching diodes to each of them and then splicing them together and attaching to the single wire from the light work or am I confusing the subject even more? The ground for the light would be thru the socket to the headlight bucket and back to the frame.

The side for the tail light also needs a resistor ,1/2 Watt, 500 Ohms or thereabouts. So what you end up with is on the parking light wire you have a 500 Ohm resistor, and a Diode, and on the turn signal wire there is just a diode. Then the two wires are connected together, and hooked to the wire on the socket. In use, with the parking light on the power flows through the resistor, and through the diode, but can not flow to the turn signal wiring because the diode in the turn signal wire acts as a gate to keep the power from flowing back into that wire.  So you get a lower voltage to the bulb so the light comes on but not as bright as it could be. With the turn signal turned on the 12 volt power in that wire cant flow back the parking light wire because that diode acts as a gate, so the bulb sees 12 volts and gets brighter, until the flasher blinks, and it reverts to the lower voltage.

A diode acts as a check valve for the power, it can flow one way through it, but not the other way.

Thank you. As they say "a picture is worth a thousand words" is true.  I will use your description and pictures to complete my project.

there are sometimes interesting Leds that might work with some resistors to install..

there are also some interesting mounting lenses for the 5 mm leds

I went to eBay to buy some diodes to complete my headlights, now I am thoroughly confused. I get online and there are so many different ones I am not sure what to buy. There are;
  13.0 volt 5 watt zener diode and
  1 amp 1000 volt rectifier diodes and
  3 amp 200 volt diodes
What do I need to purchase and what are the differences?

[enjenjo]

You need rectifier diodes. I used three Amp. The resistors I used were 1/8 Watt, 2200 Ohm.  Just about any of these resistors will work.  https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=2200+ohm+carbon+film+resistor
