Green Tint To Amber Lense When Changed To LED

Postby patbrandon1 » Sat Dec 07, 2013 2:11 am



I changed the blinker on the back of my 1982 Honda Goldwing 1100 Interstate from a standard bulb to an LED 1156 BA15S WHITE 36 LED TURN SIGNAL. It seems to me that it has a slight green tint to the LED. Anybody else notice a slight color change when changing to LEDs in your amber lenses?

I was pleased with the brightness of the LED, but just wonder if the slight color change is normal.

I got the bulb just when it turned dark, so I made a video of the difference in the dark. Maybe tomorrow or Sunday I'll take a vid of the difference in the daylight.

You should be installing an LED bulb that is the same colour as the lens that will be in front of it.

Exactly. LEDs put out a very pure, narrow-spectrum monochromatic light. Regular incandescent light bulbs put out a very wide spectrum of light. For regular light bulbs, the lens easily filters that wide spectrum and only shows what you want (i.e. amber). If you put a blue LED behind a red lens, you'll see almost nothing.

White LEDs aren't actually putting out a constant wide spectrum of light like incandescent lights do. They put out a mixture of red, green and blue, which when mixed together, produce white:



You'll notice a dip between the green and red filters - that's the amber color you're looking for. So by putting an amber lens (filter) in front of the LED, you're effectively trying to filter out all colors except the one it doesn't produce much of.

Human eyes are most sensitive to green colors, so of the remaining colors that do force their way through, your eye picks up the greenish hue easily, making the light appear greenish.

Thank you gentleman. I did look around on the net for info about this, but didn't find much. I appreciate your knowledge, and have learned a good lesson about LEDs.

I bought mine on eBay from this seller. Two years and so far no problems with the bulbs.
