I fitted switchback led bulbs onto Debbie's beetle last year .
Took off the orange and clear front indicator/sidelight lenses , and fitted all clear European lenses .
It would be no problem if there was 2 bulbs in there , one for continuous and one for indication but like the porsche it uses continous power to the bulb for sidemarking and switches the signal on/off when the indicarors are on , so I couldn't just fit one clear and one orange .
So I installed the switchback led single bulbs .
They light up white when she's driving , but flash orange when she indicates .
No problems with the cops .
They work by changing the colour dependant on a continuous 12v supply or a switched on/off .
Pretty neat but they didn't make them to fit porsche side reapeters when I was looking .
