Recently my brake lamp light is on in the odometer. Then I noticed that the brake light in my rear windshield window is not working. Then, I look inside the trunk underneath the brake light, I see that you have two sockets for the brake lamp, I replaced one of the bulb. However, there's only one connector so only one bulb is working.

I believe the other connector connected to my rear spolier that has the brake light as well. Is there anyway I could get the two bulbs on my rear brake light working as well as the spoiler light. Do they sell a splitter to split the connector cable? or is there supposed to be 3 connectors in the trunk? otherwise, if someone install a rear spoiler, then they should sacrifice half of the brake lamp in my rear windshield window?
