Ask for an advertisement online, and you will get extra points if you are good.

Your request is neither fish nor fowl, highlighting the characteristics does not mean saying everything. Your product has few functions, but it is very sophisticated. Advertising language is not a manual, and all similar products will have these functions. You can choose to highlight your brand or your performance. Either highlight your own characteristics. You'd better add your brand elements to your product promotion. Name: XX car emergency light.

As customers of the products here, they already know the general purpose of such products when they pay attention to your products, and they want to see your characteristics. Like all lights. We all know the difference between street lamps and lighthouses. As a ship, people don't pay attention to street lamps, they use lighthouses. So, don't pursue perfectionism in advertising language!

My suggestion is: XX lights a small orange lamp for you! (xx is your brand name)
