Since the LED back flap lighting from KIA is simply too expensive for me, I decided to rebuild it myself. More than 90€, without mounting, for 2 LED projectors, cables and some small stuff is already heavy. I ordered the following parts: 2 pieces Alu COB LED Spot screw type-1, 1.2W, cold white 2 pieces AMP Superseal SET 0.3-0.5qmm, 2-pole 2 pieces junction clamps 0.25-0.5qmm 5m FLRY vehicle line 0.35qmm, red 5m FLRY vehicle line 0.35qmm, orange material costs are close to 20€. The installation instructions are available at MOBIS-Parts.
