headlight needs to be replaced monthly

For the last two years of owning a Mahindra XUV 500 W6 I had to buy globes for both my headlight on a montly basis as they keep on blowing, I really had enough of replacing it every month and the risk I am in as I am travling long distances and suddenly I only have one headlight working. Most of the branches including head office knows theirs a problem with the headlights, which is a huge concen.<br> <br> It just cost me another R450 yesterday to get both lights replaced at Mahindra, as I am going to Nelspruit on Monday morning and need to have working headlights. You maybe need to inform ALL YOUR SALES PEOPLE, TO TELL ANY CUSTOMER BUYING A MAHINDRA XUV 500, THAT THEY NEED TO BUDGET FOR R450 MONTLY TO ENSURE THEYCHAVE GOT WORKING HEADLIGHTS. I need this problem resolved ASAP !!!!!
