Remember that 21 W of capacity in lamp is optimal for 2011 year vehicles. But with replacement of R8 5.2 turn lamp for 2010 vehicles needs good choice. Turn lights of Audi vehicles with 5.2 motor don’t need to be changed often. It’s vital that turn optical devices in Audi R8 work in proper way. When buying these optics for 2007 model year cars, make sure they suit vehicles with BYH engine number. Nearly all turn light bulbs of Audi have requirements at 12 V of voltage. The only possible base type for R8 signals is Bau15S.
It obviously tones the glass in 4.2 engine vehicles with model code of motor CNDA. But if the glass isn’t damaged in Audi R8 turn lamp, replace the bulb only. Make sure you purchase exactly Bau15S type of base and install it into 2012 Audi R8 quite carefully. One of destroying factors is over 12 V voltage lamp and bulbs having more capacity than 21 W.
