Yes, there are kits available that allow you to mount an LED on your dashboard to indicate when your headlights are on. These kits are typically designed to be easy to install and use, and can be found at many automotive supply stores or online retailers.
Alternatively, if you prefer to do it yourself, you can run a couple of wires from your headlight through the firewall and connect them to an LED mounted on your dashboard. However, if you are not experienced with automotive electrical work, it may be safer and more reliable to use a pre-made kit.
Remember to ensure that the LED is properly grounded and that the wires are securely connected to avoid any potential electrical issues.
