^ think he meant H8 for the size. I bought angel eye LEDs from a private seller but it was CREE LEDs. I think there are plenty out there that sell them - check ebay. The LUX version 4s are probably the most popular but also the most expensive option. I paid $100 and LUX go for ~$300(?). Either way it's a very simple replacement... twist - remove and replace the cap, and same with the bulb. 5 min job. Bear in mind that due to the design of these halos, the inside pair (closer to the kidney grill) will always illuminate brighter than the outside pair. Even the LUX. Here's a pic of mine:

As for the interior lighting, here was the thread I followed:
