If you mean the direction indicators in the instrument cluster then you can reach under the dash and pull the bulb holder and swap the bulb by feel. There are about 8 to 10 bulbs in the cluster so make sure you get the right one.
It is much easier with your head under the dash and much more difficult if you have AC fitted to the bottom of the panel.
The cluster is fairly easy to remove, 4 butterfly nuts at the corners and it will drop backwards and down.
