How do you change the direction of lighting?

The direction of lighting can be set by either changing your position relative to the light, or by moving the light source. If you’re shooting with artificial light, e.g. off-camera flash, then moving the light to give the directional lighting you want is pretty easy.

What’s the difference between back and front lighting?

Back Lighting. Back lighting is not often used as a single light source. As the name suggests, it involves lighting the subject from behind, which will not give any lighting on the front of the subject. So an additional fill light is often used to add some front or side light.

Is there a turn signal for both left and right?

Although some models use a separate light for the left and right turn indicators, other models use a single light for both turns. If your instrument panel has only one indicator light for both left and right, check the flasher unit. Some vehicle models combine the brake light, taillight and turn signal into one light bulb.

How to test for power at the headlight / taillight?

You need to use a digital multimeter to test for power at the headlight/taillight. Set the digital multimeter to DC voltage current. Turn the turn signal switch or hazard lights on. Measure voltage at the turn signal socket. You should get between 11 and 14 volts.

Why do my tail lights stay on even after I Turn Off the car?

Thank Kevin. If the tail lights are illuminated even after you have used the on-off switch to command them off, that means the switch supplying power is fused shut and/or the circuit is being powered when it is not supposed to be due to a wiring fault.

Why is the right turn signal light not working?

Back probe the wire that supplies power to the right turn signal lights; the test light should not light. If the test light illuminates, replace the switch. Repeat the test, but this time operate the switch so the right turn signals light.
