my brake light not working and a signal lights
Could be a simply bulb replacement, just make sure you've clean the contact/lead points from any oxidization. An emery board/nail file would suit this purpose. if this does not correct your issues, you may need to check the fuse and wire harness for any shorts.
Can you please explain a little about what im gonna before I brake something please
brake or break.. n/m The nail file is used to clean/scuff the contact points locate within the electrical wiring harness where the bulb plugs into. In some case, today bulbs can be halogen and can't actually be touched without proper gloves etc.. If oils from your hands gets on these bulbs, the bulbs life span is cut short.
