737 mcp green indicator bars brightness

good evening dear people of CockpitSimulator,
today my mcp and efis have been delivered and i love them!
congratulations on these products and i can not wait for what you will develop in the future!

one question, the green indicator bars on the buttons (LVL CHG, HDG SEL, etc.) aren’t too bright when at maximum brightness, in sim the light toggle is set to bright, they are dimmed when using the dim toggle, together with the digits. Is there any way to make them a bit brighter?

kind greetings,

I am having same problem. The green lights are barely visible when panel is illuminated.

Maybe the green light is slightly dimmed now. When we first tested the product, we found that the light was too bright, so we replaced the current light.

Yes, the green indicator lights are definatley way to dark. In a room with daylight they are not or just barely visible. On the real MCP they should be perfectly visible even when the sun shines into the cockpit.

Is there any way to tune this via a future firmware update or did you use other LEDs which have a lower maximum brightness?

Best regards

Currently there is no solution. We will consider upgrading it in subsequent products.

What will be a solution for us then? Because multiple people are saying the lights are way too much dimmed. Will this be a firmware fix or can we get a replacement of the new modules with fixed lighting?

It’s a great product, but this annoys me when flying.

Hoping to see a proper solution!

Kind regards

I just got my MCP this weekend and was afraid that the green indicator brightness would really bug me. Fortunately it is not THAT bad. Of course it would be gerat if the green indicator would be a tad brighter, but it is not totally unacceptable because at least in my lighting environment I can clearly identify the activated modes (and you’re supposed to check in the PFD anyway :slight_smile: )

Yes it is dependent on lighting conditions. During daytime it is not that much of an issue. Issue is most serious during evenings and nighttime when there is no sunlight and you have lights on in the room. For the price tag of the product this is unacceptable flaw. I am also interested in what kind of solution will they be able to provide.
