LED warning lights?

[Toobuilder]

Digikey has a million different versions. I buy them by the dozens and just use them all over the place when needed. Even the tiny little push in versions (#30 hole) are plenty bright in daylight if close to your sightline.

Oznium Brightest Light Bolt - Flush Mount 12V LED Light for Bumper, Grille, Cars Interior, Dash, Ambient Lighting, Motorcycle w/Sleek Aluminum Housing & Screw Nut (11 mm Black, Green LED)

I have the other LEDs and they are not very bright and hard to see in bright sunlight conditions.

You can mount them flush, or put the spacer under the LED to set it up from the panel.
The only negative I have is that when they are turned off, you can't tell what their color is, since they don't have a colored lens. But, when they are lit, there is no question as to their color. I used red, green and amber but they also have white and blue.

Got a selection of all 3 variants today, Steve, (3W, 1W with and without lens), and the 1w without lens is perfect. I'll post pics after I get them installed, Many thanks!!!

Here's a test panel I made up, from L-R are 3W domed, 1W flat, and 1W domed lights. http://seareybuild.blogspot.com/2020/05/get-juiced.html



I really liked the 1W flat light, but it's way too bright, and for various reasons I can't put a rheostat on the lights. A hangar neighbor owns a sign shop and he's suggested overlaying some self-adhesive colored vinyl, when I get home next week he's going to bring some by for us to play with.

You can always experiment with fixed resistors in series to bring the light level down. But getting a brightness that works both day and night is hard.

That's another option, but, KISS. I won't be doing much night flying in the SeaRey, but I do love seeing a sunset from the air, an occasional full moon flight, or those times you have to take off early for something.

Update: after wiring in the too-bright bolt lights and getting ready to play with some resistors I noted that Oznium makes indicator LEDs, I've just ordered some and will report back. https://www.oznium.com/led-bolts-pre...ndicator-light

I also found the post lights to be too bright, but I really liked the size and height of the 11MM post lights so I decided to dim them down.
FYI a 10K ohm resistor dimmed it down just right.
They would be perfect to light up a baggage compartment or something, since they are so bright out of the box, so I might install one in the rear baggage compartment of my RV8 just for grins.

Agreed, Steve, I also like the size/height/looks of the 11mm lights, thanks for the size of the resistor, I was about to start experimenting with a couple sizes when I got home (Oz recommend a 30 or 50 ohm one, fwiw), so you've saved me some trouble.

Just an update, Steve, I tried a few resistors starting with 10 ohms and going up to 50 ohms, all ended up being too bright. Much as I aesthetically I like the 11mm, I'll have to go with the smaller indicator lights. Oh well.

Forgive me if I’m anal about units, but in this post you say ‘10’ and the previous post ‘10 ohms’. On the post quoted it says ‘10 k ohms’. 10k ohms is about the desired value (k=1000). 10 ohms is way too small.
