You're going to hear all SORTS of opinions on incandescents vs LEDs/clear vs amber. Hot vs cool bulbs. I found the amber lens on my porch light
(to which we burn VERY little...too close to the door and bugs) DOES help a little and by keeping my lights
off in my Scamp
when I'm in and out a lot helps as well.
The wife and I finally settled on the "Tiffany" cups that Camping World use to sell. I was very skeptical about them having the incandescent C7 bulbs. What I wound up doing was going to Lowes and picking up a "dimmer". When the bugs are raging, I simply turn the dimmer down and so far, it's helped a 100%. Not a total fix but it does help and it should help for ANY ac incandescent bulb. Plus, this dimmer had "toned" down our area from the C7 brightness. Again, we've really been happy with this setup.
Here's the link to the dimmer I bought. You would have to check and see if they're compatible with LED's if that's what you're using.
