Nice work
>Here's a followup to my 12/18/15 query re LED replacement bulbs for my
>CORSA dash. I competed the changeover this past weekend, and had been asked
>by a few folks to share the results.
>Let me say thank you up front to those who offered input and insight to my
>efforts on this project - it all came in handy as I moved forward.  That
>said, here's a brief illumination background...my goal was simply brighter
>gauges and this project provided a modest education about candle-power and
>lumen conversions.  Since LED bulbs are measured in lumens we'll go w that
>term.  Standard CORSA dash bulbs are basically a combination of ba9s 1445
>and 1895 "warm white" incandescents delivering 8.8 and 25 lumens
>respectively.  The 1445's are for the blinkers and bright light indicator,
>and the 1895's handle the rest.  1816 bulbs have been used as an upgrade to
>the 1895's and upping brightness to approx 35 lumens.  check the shop
>manual for specific info.
>LED replacement bulb options varied widely but basic considerations came
>down to these...illumination path, bulb depth, color choice,
>brightness/lumen preference, and simply accepting that LED bulbs won't dim
>with the standard dimming knob.
>Research and above-mentioned input steered my decision to go w ba9s 34442
>5-led bulbs in "warm white" (available at ledlight.com).  These bulbs met
>all the above criteria while putting out 60 lumen (a big upgrade) w a
>120-degree illumination path.   They were also an exact fit replacement for
>the standards - very easy to swap, the hardest part is removing the dash
>(thx to that cursed push-down button on the light switch behind the
>Note I opted not to change the idiot lights as they have a specific job to
>do that I didn't want to mess with.
>As for the results...I'd say a nice improvement overall. Gauges are
>definitely brighter, and blinkers and bright lights function as they
>should. I'll give these a thumbs up and look forward to hearing results
>from others.  On a bigger scope, the bulb switch was part of a longer list
>of dash items in need of attention, the most visible per the attached pix
>being that I also swapped the standard gauge cluster for a "white" gauge
>pkg. so would be interesting to see how these same bulbs would look in the
>standard gauge cluster.
>The attached pix show the dash with lights off and on, and also pic of the
>1445, 1895, and 34442 LED bulbs for size comp.
>Happy to answer any questions, and thx again to those who helped me up
