well i just finished drivers ed so i think i would know since i did three point turns 2 days ago, so yes you do have to.
turn your turn signal on
You have a turn signal light-bulb out .
To warn drivers that the light is about to turn red and allow for human reaction time to the change.
the bulb with two elements in it is the turn signal and brake light bulb
To change the turn signal light in the 2003 Subaru Baja you need to have a tool box with the necessary tools. Open the screws to access the turn signal light and replace it.
That's the point. So people behind you know you are turning.
If there is a light labeled right turn signal and it is red, you can not legally turn.
The turn signal light can be accessed from the back of the turn signal light assembly. Push the lightbulb connector in and turn at the same time. The lightbulb will come out and can be changed.
if the front signal is working and the back doesn't, the light is probably blown.
The front turn signal light bulb can be accessed through the engine compartment. Take hold of the light bulb connector on the back of the turn signal. Push the connector in and turn at the same time. The light bulb will come out.
Definitely sounds like an earth problem from your turn indicator. Check your earth wire from the light cluster especially from the turn signal. If necessary splice in a new wire to a good earth point this will stop the tail light flashing.
