Gave her a good wash yesterday and predictably the indicators immediately failed I really thought I had fixed that, but apparently not. No problem though, a couple of minutes with a heat gun (paint stripping) dried most of it and then they started working again on the way back from the gym once the engine heat had dried out the flasher unit.
Today followed a friends suggestion and replaced one of the
rear clusters with an LED cluster (he struggled to see my indicator
following me in bright sunshine)
Only did the nearside as a 'proof of concept. First impressions not
good. Difficult to quantify it while just in the garage but the LEDs
don't look half as bright as the originals. And with the lights on
the extra illumination of the brake light is minimal. Having said that
they were extremely cheap Chinese ones and the indicator has only 5 LEDs
and the tail light 5 LEDs with an extra 2 for the brake light. This
compares with the 32 LEDs on my high-level brake light which works
extremely well. So maybe I need to find some with a lot more LEDs.
I'll leave it on for now until someone can follow me in his car and
test them properly, but I suspect I will finish up going back to the
original bulbs, maybe polishing the reflectors a bit.
