If you want the correct bulbs that will fit straight in you can get them from Holden but take plenty of money with you. Otherwise you can take the old bulbs out and go to Jaycar and find something suitable that you will need to refit to the bulb holders
Hey mate only just did this on my ute, take out your old ones, go down to autobarns or what ever u got as a local auto parts seller, and by a replacement, i bought LED ones for my car they are the T5 type LED's, they work pretty good but don't light the whole thing up, more focussed on one area, but that's cause there LED's
