I 'am on my third attempt on the dashboard lights!Looks good now. Image Unavailable, Please Login Vidéo: https://streamable.com/s4q0l Initially I installed some leds but these were not bright enough (much better than stock), the beam was so-so (all the lateral leds are useless given the design of the gauges), and the colour a bit blueish. On top of it these would not easily fit without some persuasion (had to butcher them a lot). Image Unavailable, Please Login As a second attempt I reverted back to higher output regular bulbs and upgraded the rheostat windings with thicker nichrome wire (Ni80 available in most e-cigarette shops). The illumination was quite nice but once factoring for the numerous bulbs (10) the amp-draw was quite high and I was afraid the heat would damage the 40 years old gauges. That's a good solution for whoever wants to keep the car stock though. Image Unavailable, Please Login Image Unavailable, Please Login As a third attempt I gave leds another try. This time I decided to build my own bulbs: unlike BA9S, G4 bulbs are offered in numerous sizes and outputs, the idea was to fit these onto "BA9S Lamp Bases Socket". So I selected some 90 lumens dimmable leds (that's theoretically 10 times the power of the stock bulbs, much less in practice).

I've left the instrument pinnacle enlightened for 1 hour at 75%power, no significant heat. My only issue left is to find a proper dimmer that modulates the positive wire : the ones I bought are modulating ground which is a problem as ground is shared with other elements of the dashboard and I want to keep the wiring stock.
