I have a '99 Disco 1 and in the last week my Left turn singnal has started to blink realy fast when it is turned on. It did not do this before and the right does not do this. The four way blinkers blink at a regular speed also. Anyone hurd of this or know if there is a fix?

 

Typically, that indicates thatyou've got a blown directional bulb(front or back).

 

When you start replacing them, replace all the bulbs that are turning grey or black and do it in sets.

I checked over the weekend and all bulbs seem to be working.Not sure what to do next?

 

Clean all the connections and especially the sockets.

All 3 blinker bulbs are working? - any of them being out should cause a fast blink.
Do you have any LED bulbs? - they don't have enough load.

 

I am running the 7 bulb led light and have not had any problems with them.

Disco 1, have you tried cleaning the bulb sockets, even if the lights are working a dirty socket will cause you grief.
