Burned Out Bulbs: In the case where only one of your rear lights appears to be out, the cause is most likely a burned out bulb. When the filament breaks inside a bulb, it cannot illuminate the gas inside the bulb. A vehicle with a bad relay or bad ground may not be able to successfully power your rear lights.

Damaged or disrupted wiring can cause tail lights not to work, but brake lights are. The two lightings use different wiring as each bulb has got its power supply. So, the breaking lights might be working if their wires are not damaged. This problem occurs when you have severe or lose power cables.

It could be that the dash and taillights share a common fuse. So, if you do find a blown fuse, you’ll need to track down the reason it blew in the first place. Other potential causes for your problem include a short somewhere in the circuit or a faulty light switch.

According to The Spruce, it’s possible your fuse is short circuiting due to loose wire connections, damaged wires or an internal wiring problem. You can continue to fix broken fuses, but when the root of the problem is deeper in your electrical wiring, it’s best to call in a professional electrician.

The cost to upgrade an electrical panel varies depending on the scope of the project and the type of panel. It could cost as little as $200 to upgrade an existing panel, while replacing an entire fuse box or panel could cost $1,000 or more.

The national average to install or replace an electrical outlet is $212. A new one can cost as little as $75 or as much as $485. The project typically ranges from $132 and $291. Each receptacle unit will cost between $3 and $50 depending on the type you need.

However, new codes require them to have at least one 20 amp circuit with at least one GFCI protected duplex receptacle for each vehicle. Wiring a garage to this minimum costs between $2,000 and $3,000 on average.
