I just installed mine in the p500. They are also straight out like yours but not quite as far. I was able to bend the wire down and get the cover back on...hope it wont damage the wire long term. I purchased the xentec brand for $22 on ebay. Super easy install, took less than 5 min. They look great but do flicker a little, not sure if this is normal or not.
I got OPT7 Bolt series kit
