light bulbs are hot because the coils spread heat around the bulb.
Turn signal bulbs and hazard bulbs are the same bulb. When the turn signal is turned on, the indicator light on the dash flashes in tune with the turn signal. When the hazard lights are turned on, an extra fuse which is live, powers the hazard flashers, even if the car is turned off.
The dash light dimmer switch is turned off or broken.
No.. but u do have OCD if you keep checking if all the light bulbs are turned exactly 36 degrees to the right
The fridge light should turn off when you close the door. The light is hot because not all the electricity is turned into light - an awful lot is wasted in the form of heat.
The panel light dimmer switch is turned off. The panel light fuse is blown. The panel light bulbs are blown out.
With all lights turned off,have someone step on the brake pedal. The bulb that illuminates is the break light bulb.
The filament in the bulb gives off light.
Heat.
Because, if it wasn't for heat, there would be no light at all. The sun is blazing hot and gives off light. Our light bulbs require heat to produce light. Many other things.
Incandescent bulbs or if you prefer, plain old fashioned light bulbs, the ones with a filament (the bit of wire inside) that gets very hot and gives off light. They tend to give off a bit more at the red end of the spectrum, particularly the lower power ones but they do give off all the colours. Some run the filament at a sufficiently high temperature to give a pretty balanced white light. Most of the modern energy efficient bulbs give off light at a limited number of frequencies but much more light per watt of power that goes in.
Be sure the dash light dimmer switch is not turned off and the fuse is okay and the bulbs are good.
Assuming the bulbs are good, the dash illumination light brightness control switch is turned off or broken.
