I hardly ever fly at night since I retired from commercial flying so I now always use the landing and taxi lights during the day for collision avoidance. I replaced the 55 watt halogens with 100 watt halogens and it was a nice difference however I didn't realize how yellow they are until I installed an LED. Also notice the how clearer and brighter the grass looks with the LED. BTW they are $20 H3 LEDS and they produce no noise in the comms either. It doesn't have to be an expensive upgrade unless you want it to be.
Now I have 2 LEDs and installed a wig wag too. Click on the picture below for a short sample video:
