LED LIGHT PANELS

Riddle me this.....

If you have "white" LEDS they would (I assume) emit all frequencies of light, red being part of their spectrum ?
If you have red LEDS they (mainly) emit the red part of the spectrum ?
Now, if you put a red lens over a red LED ( in theory, a red filter blocks all other frequencies other than red ) you would get close to100% transmission...wouldn't you ????

Why then do I see in Nippy Normans that a red lens should not be used with red LEDS ????

I obviously am missing something here, can anyone elaborate....:nenau

Reason I ask is that I like the added intensity but don't like the "boy racer" image of clear lenses. I know the later versions had/have clear as stock but "I" (just one persons viewpoint here) think it makes the bike look "cheap"...

the voice of reason .... :thumb

Interestingly, I have just found this quotation from a greed bay vendor...

Important: A lot of people misunderstand the colour choice for an LED bulb. A red LED will work better behind a red lens than a white LED! An amber LED will work better behind an amber lens than a white led! Both colours will work equally well through a clear lens.

In discussions with Norman I am told to expect illumination better than the stock bulb with the stock red lens fitted ( good enough for moi) & have placed an order. Why Norman instead of a "cheaper" vendor ? Unsurpassed service & quality of product....:thumb2
 
Or if you're a tight fisted git there's a thread around somewhere showing roughly how to fit some hyper bright LED strips from Maplin, might be in the tech section :augie
Not linking cos that might be a bit rude :thumb2

Been reading both & find them very informative......:thumb2

Installation complete... Apart from being "brilliant", I like the attention getting "visual snap" of LEDS......:clap
 
I simply put 4 red Leds in the reflector. 2 wired to the brake light and teh other 3 wired to the tail light. Works perfectly and if the bulb blows I still have the LEds for both brake and tail lights.

Instead of the red fading to the outside of the lens the whole lens is the same intensity. Put on the brake light and its like the coca cola christmas advert! :)

Yep, well NN lights look great but I cannot justify that sort of money!!!!!!

So I have also modified my rear light unti to add LEDs so that if (when) the rear bulb blows, the leds still provide light, altho' didnt feel it worth while to include brake light leds!

parts cost me around £10, for the leds, from
http://www.ultraleds.co.uk/product_...=1135&osCsid=6e477a473e084d332dd8bcaf85a879ae
who also supplied the resistor ballasts needed for leds.

wiring was relatively easy, using the leds anode and cathode themselves and simply daisy chaining them as can be seen from the photos!
drilling the plastic light carrier for the leds require a 5mm drill and ability to measure reasonably accurately to obtain a fairly circular eefect around the existinmg light bulb and also avoid the strengthening ribs on the back of the light...its a doddle really!!

OR you could just pay £60 ish to buy one!:augie

and some piccys!!

I also acknowledge that I stole the concept from the excellent wide running lights thread, from a while back, adapted to "just do" the rear light being a lazy so and so! so search on that for more great detail and see who had the orginal idea:rolleyes:

i did this, but its so bright, i think i may have to take out the origonal bulb, i don't have abs or the bulb monitor thingy, what i also did, is fit a set of the led strips in my top box, well 3 sets, two as stop lamps and one as side lamps, into thw red central bit of my givi top box, looks awsome :augie

I've been thinking of doing this too any chance of posting a pic or two?
 
No link cos this is Normans thread but you might try a search for "Beefed up my rear" ;)
note to self be more specific
I meant the top box thing as I have a kappa 48 with a lot of red plastic lens begging for something bright behind it other than me :D
I did spend quite a long time going over past threads but without much luck
 
An alturnative to LED's

For many years now I have changed my standard tail/brake light for a deceleration modulator by Kisan.
The manufactures says "TailBlazer overcomes this by rapidly flashing the taillights the instant you apply the brakes. The flash rate then slows down to a steady ON - this cycle lasts about 4 seconds. This flash pattern is called a Deceleration Warning."

I dont know if its legal in the UK so have a read and make up your own mind.
go to:http://www.kisantech.com brake light modulators. I have never been pulled over for using it and the bright 20W halogen make me feel very secure when braking and riding at night.

Safe Riding

My worries would be inducing a grand mall seizure in the following driver/rider & have him/her barrel me up the ar$e....:blast
 
I just had to change the winkers too...... :thedummy
