Fogged up headlights are a serious danger to yourself and to other drivers. If you drive around with headlights that are less than optimal like this, then you are at serious risk of getting harmed in an auto accident. We need to have maximum light coverage from those headlights when we are out driving, and that means we require that the headlights be cleaned and maintained regularly.
One of the best ways to maintain your headlights is to use insect repellent to get the DEET chemical on them that will allow you to keep them clean. You may not immediately associate DEET with cleaning headlights, but it is known to be good for that. The only thing to make sure of is that you don't get the insect repellent on the paint of the vehicle by mistake. It is easy to have that happen, and it can cost you dearly in terms of that paint.
