A few question if I may;
Do the 9006 (I assume) zxe's bulbs have caps on ends like the OEM's SEE pic?
Are the parking LED's blue tint and which pic is more representative?
Any concern in blizzard or fog with glare or light /reflection back into drivers eyes from LED's ?
Here's a decent thread with experience and info on the Sylvania zXe bulbs from the HID Planet forum:
