increasing the amount of response time
increasing the amount of response time
Below is a few words taken from a Google video about LED lights. The whole article at the Google page. What is says is," LEDs come on faster and increasing the amount of response time as much as 19 ft at 65MPH. Pretty interesting!
"LED lamps promote safe driving by increasing the amount of response time available for motorists. That's an extra 19 feet of response time at 65 mph for the trailing vehicle. [Distance traveled = (mph)(5280 feet/mile)(1/3600 hour/sec)(0.2 sec.)] The results? Less rear-end collisions, which are the second most frequent type automotive accidents."
Although I do not agree that cluster bulbs are the way to go on tail lights because they spread out the light and you don't get as much light output. The over all idea is right. LED do come on faster.

LED Voltage
Dan:
These are rated to 13.4V.
They probably work great on the back end of a trailer, but would they work on my Clipper motorhome. I have the tail lights on a 30A relay and juice feeds right off the rear mounted battery. When I am running, with DRL on, the battery voltage shows over 14V on the digital gauge.
Will these stand up to that voltage??

This light kit will work in two different style lights. We call it a 4.25 by 4.25 because the lens measures 4.25 by 4.25 inches. If your tail lights look like the below pictured lights it will work in your unit.
Our fix is 4 red pads with 1157 (BAY15D) sockets

14 volts and no higher

Dave,
We have designed them to handle no more than 14 volts. The reason being, the larger the voltage range the less light you get. We designed these for the 4.25x4.25 lens listed above because those are so dim on older units. The more pop (Light output) they have, the safer it makes night travel.
We are working on a fix your unit and I'll let you know when we do.
Thank you for explaining how that circuit works.

This doesn't seem right or whoever designed the regulator (or just a clump of dropping resistors?) missed something.
An LED is typically a 1.8v device, with a specific current flow for optimal lumen output. Ohm's Law plus/minus regulator design should be able account for optimal lumen output/current for almost any voltage range from 6-18v or more - it's done in 120v home devices, no reason it cannot be done in a 10-16v vehicle system with less waste.
Battery and vehicle charge system values and performance have been well-known for years. 10v is a dead battery. 12.6 is a properly charged battery at rest/open-circuit. 13.6 v is typical sustain/run voltage. 13.8-14.8 is the charge/saturate voltage range.
If the vehicle system is running over 14v routinely then it is trying to charge a stubborn battery, or will boil out a good battery. But I would not expect "lower light output" during the post-start recharge boost period - that's a separate lighting device design issue.

This kit is no longer sold. When we came up with this kit it was mainly designed for the Airstream trailers where the tail lights were so dim. People needed something to make their unit visible on the road.
Once we came up with a better product we discontinued this kit.
The new kit is LED-kit2 which is a water tight sealed kit that handles 12 to 24 volts.
Click here to see the LED-kit2
However, this kit will not work on the Motor Home in this post. There are two or three different ways to go. If that unit has the tail light that I listed above"a picture of a light Airstream uses in their 2006 Classic.(above 5-26-2011)" then you could go back with what that company offers today (star-burst) or convert to Bargman.
I would need closer pictures and measurements to be 100% sure. There is an LED up-grade for that unit.

this is the old kit
Wow, I was searching the forums for something and ran across this. Just in case someone is doing the same I took down the old pictures and have to say there is a new kit
LED-kit2
