Today, I received Hella Chrome Trumpet Double Horn Set, costing ₹
1,209 from Amazon. I liked the trumpet horns. Since Blue Diamond has already completed the warranty period, I need not bother about cutting and splicing the wires. I drove to United Motors Bosch Service, Rajajinagar, Bangalore for fitment. The front grill, bumper, etc. were removed for fitting the horns. Two technicians took two hours to complete the job. Apart from this, Blue Diamond required some attention too. The wiring for front and rear dashcams and HUD were not fully concealed as it was done by me at home. So, I requested them to conceal the wiring fully behind the panels, A, B and C pillars. Also, the battery tray had some salt deposits, which needed through cleaning. The technicians took another hour or so to complete these tasks. The owner, Mr Dhiren Mehta suggested rubber coating of the tray and fixtures to cover the corroded areas. I agreed. He himself came over to the washing area and sprayed the coating on the battery tray. On the whole, three hours well spent for the upkeep of Blue Diamond. I paid ₹
1,414 including spares [wire, connectors, clips, etc.] and labour.
