[Healeys] LED dash lights

LED are voltage sensitive and if the input voltage drops below the requirement (12v) the lamp most likely will flicker.  This is unlike the incandescent lamps that just are a bit dimmer in this situation.  Check the voltage at the lamp or at least at the output connection of the control switch. I’m not sure why they ultimately fail but the do.

I bought a set of LED dash lights from British Car Specialists last year and they worked great until recently when I noticed they started to flicker.  This has gotten worse until yesterday morning the speedo light never came on and the tach was dark for a while before beginning to flicker.  All 4 gauges are exhibiting the same symptoms, but the generator light, high beam indicator and trafficator indicator function normally.  All LED bulbs are tight in their mountings; I can rule out intermittent contact.  I’ve not swapped the incandescent bulbs back in yet for a test, BTW.  Any thoughts on the cause?
