Light warning, err, light.

Hi All

 

Simple one really, I lost a brake light (drivers side outer, took the cluster off and found it was a loose wire, I thought ok lets turn this into an upgrade and changed all 4 brake lights for LED P21s and soldered the wire back on.

 

Couple of questions though.  The warning light is still on on the dashboard, how do I stop that? it went away briefly but was back on this morning a day later even though all lights work.

 

Other question is I was going to change the whole cluster (indicators and reverse too) for LED P21s but they only seem to fit in the brake sockets even though they are marked up as P21s on the outside of the cluster.  The little toggles dont seem to fit, does anyone else have this issue and how do I get around it?

LEDS have difference resistances to normal bulbs. Thats why it throws on the bulb warning light.

You have to fit resistors to each bulb. Somebody might know another solution mind. I know i removed the bulb when i fitted my LED lights.

For the indicators flashing quicker you can get an LED relay flasher for that.

I might switch back to normal bulbs then as they dont seem to fit in the other parts of the cluster anyway even though they should and to be honest I was not that impressed with the difference in visibility.  I will switch back and see what happens as I still have the old bulbs cheers.
