The number of bulbs in the taillight assembly of a 2016 Honda Accord can vary depending on the specific trim level and the design of the taillight assembly. In most cases, the taillight assembly of a 2016 Honda Accord includes multiple bulbs to serve different functions. Here’s a general breakdown of the bulbs commonly found in the taillights:

1. Brake Light Bulbs: There are typically two brake light bulbs, one on each side of the taillight assembly. These bulbs illuminate when you press the brake pedal, signaling to other drivers that you are slowing down or coming to a stop.
2. Running Light Bulbs: Similar to the brake lights, there are typically two running light bulbs, one on each side of the taillight assembly. These bulbs are on whenever the headlights or parking lights are activated, enhancing the vehicle’s visibility.
3. Turn Signal Bulbs: The taillight assembly may also include turn signal bulbs, usually amber or red in color. There are typically two turn signal bulbs, one on each side, that flash to indicate your intention to make a turn or change lanes.
4. Reverse Light Bulbs: These are the white bulbs in the taillight assembly, and there are usually two of them, one on each side. They illuminate when you shift the vehicle into reverse, providing extra visibility when backing up.

It’s important to note that the number and type of bulbs in the taillight assembly may vary depending on the specific trim level and optional features of your 2016 Honda Accord. If you need to replace any of these bulbs, it’s crucial to consult your owner’s manual for the correct bulb specifications and follow the manufacturer’s recommendations for replacement bulbs to ensure proper function and safety.
