You can adjust the colors of the LED, but I believe you can only have seven colors for the LED (eight if you want to set the 'off' setting to a color).
And as I have said before (and had it reinforced by other users). That LED is BRIGHT AT NIGHT. Grab your shades when it comes on.
("I wear my sunglasses at night.") Don't select Red or Blue flash and set the scanner on your dash.
LEH, I had the same first impression... but turns out you can fix this!
As near as I could tell without opening the unit, the "LED" display comprises a sort of light guide fed by three LEDs located inside the unit -- a red, a blue, and a green(?) one. [I gave my loaner back this morning, so I can't verify the color of these three LEDs].
At any rate, there is a menu branch in the GLOB tree (waaay down the list) that will allow you to adjust the output of the individual LEDs in steps from "zero" to "too bright" simply by pressing the numeric keys (for rough settings) or changing the Hex coded level for really fine tuning.
The factory setting is "too bright" for each of the three internal LEDs... : )
The output (what we see looking at the external portion of the light guide) is a combination of light from all three of the internal LEDs... and the various colors are produced by various mixtures of these.
For instance, "RED" would just be the red LED on and the other two off.
"PURPLE" would be the red and blue LEDs on and the other off.
But wait! There's more! LOL!
Since the intensity of each of the internal LEDs can be set independently of the others, not only can the whole external display be dimmed but by combining different levels of the three internal LEDs, a whole array of colors can be obtained (subject only to how good is our perception of color differences in this mode)
My hope would be a s/w mod that would add some additional space for "custom" colors we might come up with, and also an additional (faster) blink rate (or even a long/short combo, or a red/blue combo... etc).
Both of these mods would help expand the optical alert capability of this very cool unit.
