Or use local reflections to your advantage.
Or if you have installed an FPV system with something like iOSD installed, you can see the amount of connected satellites and the home point on an external display.
Or install small angled or rounded mirrors or something reflective (like aluminum foil and cardboard) under the Phantom arms to reflect colored light out and upwards for direct visibility.
Something else you could try, which I haven't attempted or researched, is attaching an extra LED to the leads of an existing LED, or possibly relocate one or more of the existing LEDs. This would require a decent soldering iron and some decent experience with a steady hand, and I have no idea how much of the LED traces/leads, if any, are exposed. I figured I would at least mention this as a possible option since this forum is a place full of modders/tinkerers/tech people anyway, and someone might be more ambitious than myself to see if/how that would work.
