It’s technically not orange light bulbs they have to use, it’s a specific lamp style called ‘low pressure sodium’
Here’s an article that explains the reasoning behind Hawaii’s lighting sources and the regulations:

Have you tried warm/hot vinegar in a spray bottle? If you have hard water it could be mineral buildup and some warm vinegar would help dissolve it. If it’s not from hard water it may be trickier, but a super soft bristled brush and some simple gree or other cleaner may work as well.
Red light is great for a headlamp when you want to preserve your night vision, you’re also walking instead of traveling at +60 mph. Red light also doesn’t provide you with any color differentiation which would be an issue with already existing road lines (yellow vs white) and street signs along with the simple notion that humans are used to light in the full spectrum from the sun.
The biggest issue with headlights is people putting LED lights in older, halogen bulb housings that don’t scatter the light the same as LEDs which leads to blinding lights that are quite bright. Additionally, you get those assholes with lifted trucks that don’t re-aim their headlights and they too add to the annoyance and danger of driving at night.
Better enforcement of existing laws would help, but that’s asking a lot of police these days when they seem to have so many other “better” things to be focusing on. /s
It’s always good to have a backup heat source if you live in a cold climate, but heat pumps have progressed a fair bit with running at lower ambient temperatures. Many manufacturers have models that can run down to, or below, 0°F. However, those models usually are a fair bit more costly, so it makes sense to evaluate how often it dips below the low ambient cutoff for the heat pump and the cost and type of your backup heat to determine the most economical route.
