Might be something in the Agricultural / Industrial equipment parts supply. Rework something from flea market find. Change to 6 volt bulbs in the ones you are considering. Concealed 12v motorcycle or garden tractor battery, as it would be short duration use. - Great truck & good luck.
Why not just convert to 12V. Just a new coil, covert generator to 12V alternator and a new battery. Will give you brighter lights and a better power supply
I assume that you only have the one brake / tail light on the left side of your truck. Consider getting another one that matches and modify the bracket so it fits the right side and use those for combination turn signals / brake lights. That is what I did and I used the system put out by Electro Tech. http://www.turnswitch.com/Turnsignal.htm
They have really worked well for me. I did have a problem about a year and a half after installing them and they fixed them with no cost to me even though it was well after the warranty period.
Having two tail lights with turn signals is a must if you will be doing any night time driving.
I tried a lot of Motorcycle lamps from Hondas to Harleys and the were all to bulky or had too much plastic chrome.
I did some shopping on E-Bay and Craig's List for some antique styled ones but they were too spendy or required a lot of modifications to make the work safely.
I eventually used a Logo Lights kit from Snyders (LOGO LIGHTS A-13402) as I had success with them on a coupe and Tudor. They mount up easily, are easy to see even in daylight and can be hidden away so they are not to obvious. I did modify the supplied Brackets to suit and tucked the rears up under the deck. Blacked out the shiny bits and wired them up easily. The control box can easily be pulled for show as it is attached magnetically to the tank behind the dash.
All in all they met my "Bang for the Buck" requirements, and have operated on all three vehicles flawlessly. Just my Two Cents, your mileage may vary.
Good hunting!
I made my own system. Went to Menards for a switch. DPDT center off, Got a beeper and flasher unit from Snyders, found some lights I liked for the frt. and rear and wired them up myself. Tip. Use black solid strand wire so you can bond it to the underside of frt. bumper supports so no one sees them. If you want more info on how to wire it let me know and I'll try drawing it up for you.
Thanks for the suggestions. Actually I have 2 tail-lights.
I think this is a good discussion that needs to be raised. I do like driving my Double A on back roads and through small towns.....so Safety Comes First.
