Cheaper to upgrade the embarassing stock horn with a louder aftermarket one than spend more for dual beam HIDs. Another place to shop for HID kits is www.groupbuycenter.com. But, beware, most of the vendors are really small (out of the garage type operations) and may not be legit.
that's exactly what I've done - dual Italian air tubes (about $20 on sale in any parts store)

Helps to "wake up" some dorks.....
