L E D lights
Why are led lights not offered in 6 volt? Would bulbs burn half bright on 6 volt? thanks Bob Brown

Re: L E D lights
Not enough demand?
BUT You can buy insert 6V LED light panel for the taillight or the 6V taillight with the LED light installed. I have a new set which I purchased for my 30 Roadster at the Barrie Automotive flea Market in September 2011 |

Re: L E D lights
Almost all LED's work off of 5 volts or less. There is just a resistor placed in series with the diode to adjust the supply voltage down to what is required for each individual diode. The only difference between 6 volt and 12 volt applications is the size of the resistor. So, with a little knowledge of Ohm's law, you can easily swap a 12 volt led to a 6 volt by just changing the resistor.

Re: L E D lights
On teacup tail lights, there is a wire that you can cut between the upper and lower circuit boards that will allow you to use the lower set of LED's as a turn signal. Believe the wire is green.

Re: L E D lights
On my 6V sedan,I use 12V LED lights for turn signals by useing the white ground wire forthe power wire & black wire for ground.You need to do it this way because the LEDs are set up for neg ground.

Re: L E D lights
These guys have 6v led bulbs. I haven't tried them yet, but they are on my to do list.

Re: L E D lights
I've been running LED 6 V + Ground from Brattons since 2005.

Re: L E D lights
I have an all red six volt tail light / brake lights built into the taillite.
In the past I have tried the 6 volt RED replacement taillite by BRIGHT LEDs which worked well. The white ones are so bright they look white through the lens. |

It's not that they are so bright, it is because the spectrum from typical white LED's is mostly blue light and almost no red. A red glass or plastic tail lens passes 90+% of red light (~625-660 nm) and only 5-10% of other colors. Look at this emission spectrum graph and you'll see why white LED's don't look red through a tail lamp lens. Standard tungsten lamps produce 60+% of their light in the red band. Red LED's produce 99+% of their light at a single specific wavelength within the red band. Most red LED's are 635nm. Never use white LED's behind a red colored lens! |

Re: L E D lights
White LED torch behind lens. Looks red here & in real life. Problem is the LED's are 4.5 volt and when 2 a wired in series they are not bright enough. 6 volts burns them out instantaneously.

Re: L E D lights
Fot sure, every point in Mikes posting is correct.
I would like to state 2 points. 1. Regarding the rear-lights i suggest to use the LED-panels to be offered by the vendors (modelastore for example ; see above) Normal LEDs with BA15 (as offered by "superbrightleds.com) are very long and do not fit to well into our backlighthousings. 2. It might be that BobBrown was talking about front lights??? Ja - i wonder too, why there are no 6V-high-power-LEDs to fit into our front headlamps. The available 6v-LEDs (with BA15 ) are way too weak for the front (and they produce this typical blue LED-light, which is ugly). Best regards Christoph |

Re: L E D lights
well - as mentioned i think LEDs (in the Headlights) are :
- ugly, - not strong enough but its ok (to me) as i want to run lights all day.... I use them additional to bulbs (which i use in the night) |
