How to choose interior LED lights for your car

Strips or replacement bulbs: which one do you need?

Accent strips add new light, usually under the dashboard in the footwells or along trim gaps. Replacement bulbs swap the factory dome, map, visor or trunk bulb for an LED version. Bulbs keep the car’s original switches and door triggers. Strips add a control box and cables that you route yourself.

Pick a power source: 12V socket, USB or hardwired

Most plug-in kits use the 12V socket or a USB port. A 12V kit occupies the socket, so plan where phones will charge. The car charger buying guide covers chargers with extra ports. USB kits are smaller but need a free USB port or adapter.

Hardwiring frees the socket and lets the lights work with the ignition. Use an inline fuse sized for the kit. Tap a circuit that switches off with the car, so the lights cannot drain the battery.

The dash cam buying guide also covers hardwire kits and fuse box power. If you are unsure about the fuse box, ask an installer.

Choose app, remote or both

An app gives the widest range of colors and effects, but you need your phone to change settings. A handheld remote is quicker for on and off. Kits with both let a passenger use the app while the remote stays in the door pocket. Music modes use a built-in microphone and change the light with sound.

Check length and the number of strips

Measure the footwells and the route back to the power source before you order. A 4-strip kit gives 1 strip for each front and rear footwell. Larger vehicles may need 6 strips or longer extension wires. Fiber optic tube is sold by length and can be cut to fit.

Match the bulb size code exactly

Festoon bulbs use codes such as DE3175, 578 or 6411. Wedge bulbs use codes such as 194. Find the code in the owner’s manual or on the old bulb.

A festoon bulb has a cap at each end, and the length must match. Some cars show dashboard warnings or flicker with LEDs, which a load resistor or equalizer may fix.

Consider color and color temperature

For dome and map lights, a neutral or cool white makes it easier to find things in the cabin. Color temperature is given in kelvin (K). Higher numbers look bluer. Colored accent strips are for mood, so keep them dim when the car is moving.

Mount and wire the lights safely

Driver safety comes first with interior lights:

Do not mount lights where they shine in the driver’s eyes or reflect in the windshield or mirrors.
Use a dim, warm or single color while driving, and save flashing or music modes for when the car is parked.
Check the local rules where you drive, as some places restrict colored lights that are visible from outside the car.
Route cables away from the pedals, seat rails and steering column, and keep them clear of airbag covers and side curtain airbags.
Secure loose wires with clips or ties so they cannot catch a foot.

Adhesive strips stick better to a clean, dry surface. A kit from the car cleaning kit buying guide helps prepare the plastic first.
