Printing clear signal lenses. Is it possible?

Kawasaki Clear Motorcycle Lens

Does anyone know if clear signal lenses can be 3D printed?

You can't get a "clear" 3d print because the print is stratified and will always refract the light pretty drastically even if you polish the surface. Visibility would be very poor even if you got a model that fit well.

Thanks Thorn, I thought there might be a problem like that.
I am just going to have to bite the bullet and order them from Custom Dynamics, pay the 20% plus exchange rate and high shipping cost to Canada if I want to install Anthony/kc2dgq's LEDs.

I have not forgot you Anthony. I will eventually get the LEDs installed and some pics posted here.

If your LEDs are red , the red tail light lens will intensify your color and will look more predominant than using a clear lens. Just food for thought.

Sort of... that's part illusion and a part missing. . .

If you have a clear LED rated at 100 millicandles, and a red LED rated at 100 millicandles, then the clear one will be attenuated by the lens filtering out the rest of the spectrum besides red. So, placed side by side, the red will look brighter compared to the clear. Also, a lens will disperse the red light better since that light is not impeded by the lens within itself ( in its material ) and so it will look larger than the LED's appear without a lens, ( given that the LED's are far enough away from the lens to develop a beam upon its rear ).

But on the other hand, if you have a clear LED that is rated at 10 candles and set behind a red lens and you hold it up to those others, the others will appear to be dark by comparison since 10 candles is 10,000 times brighter in the entire spectrum.

Last but not least... the old Thomas Edison trick of putting a mirror behind a light-bulb to catch and reflect its rearward rays of light, won't work with LED's since they are typically built to cast their light only in a very small conic section down their axial forward.

So just like light-bulbs, LED's are all different ratings, power consumption, and brightness depending on the model.

This reply might sound technical/picky, but... for more information that *is* actually more technical/picky and dispels a few myths... see here:

Hope this helps

Haven't used it ( yet ), but check out Gallery Glass, Hoss.

From what i was reading, one of the Gallery Glass products pours like plastic, hardens to the color...

I don't know where your info comes from.
Not saying the technical you provided is wrong.
I'm only speaking from 19 years experience in the sign industry.
Red LEDs make red plastic more vivid. Which is what I stated.

To each their own.

All of Ma Kaw's OEM signal light lenses are amber on the VN.
Anthony/kc2dgq built me a set of "Dynamic Cluster" look-a-like LEDs for my signal light housings.
Motorcycle LED Light Bulbs

Front facing on each side are 48 dual intensity amber LEDs for running and signal lights. Amber lens work fine in those positions.

Rear facing are 24 amber hi intensity LEDs for turn signals.
This basically replaces the stock incandescent bulbs that come stock on the bike with brighter LEDs, hopefully to be more visible to other drivers on the road.

For rear running lights the OEM lighting only provides the 2 tail light bulbs in the housing on the rear fender. Rear facing tail/running lights by law must be red. So I need CLEAR or SMOKED lens for the rear running lights.

The LED clusters add 24 red dual intensity rear facing LEDs forming a circle around the amber diodes to effectively triple my tail/running lights and my brake light intensity.

It also increases the lighted width of the back end from the 5 inch wide tail light to about 20 inch wide between the two signal light stalks.

So now I just have to order some lenses from Custom Dynamics, and an electronic LED EP34 flasher unit: https://www.ledlight.com/electronic-...sher-ep34.aspx
(none of the flashers I can find locally will work properly).

I also need a waterproof push on/push off switch for auxiliary driving lights out front.
I cannot find one locally or online.

Anybody know where I can find one?
Please leave a link if you do.

I checked out that site.... maybe my reading skills are bad, but all of the replacement bulbs are front pointing... the turn signals are at 90 deg angles stock... an incandescent doesn't care, it puts out light at all angles... so did you have to get turn signal housings for the LED replacements? If not, then how did you get around the 90 degree angle?
