so only will be on when you're in park or have the e-brake on etc...
Nope, they only turn on when you turn your headlights on, or when you turn the headlight switch to the first position (turns on front and rear parking lights and bumper lens lights).
aren't the wattage on those too high for stock celica lines? i heard the wires will melt after some time with those bulbs but not sure.
Nah, those are halogen bulbs only (headlights, high beams, foglights). Standard incandescent lights can't get hot enough to hurt anything.
^^^ don't those bulbs also somewhat help illuminate the road to an extent.
Nope, they just help other cars see you at night when you're parked and you turn your parking lights on, or while your driving and a car is on your side.
just get some HID's at 8000K like me:)
And if he's worried about visibility, those are the worst bulbs you can get. Beware the rain!
Arent parkers on whenever you SWITCH them on and not when ur parked//handbrake up??
Coz here (in australia) we have 3 settings:
1) Parkers (the wedge bulbs) (constantly on, not brake dependant)
2) Headlights + Parkers
3) Highbeams + Headlights + Parkers
oh and whats with ur DRL?? is it really needed??
Yup, those are the same settings the US have, and they work the same way (not by going into park or by pulling up the handbrake). The DRLs are your high beams at around 50%. They're not necessary unless required by law in your city/country. There should be a guide to disable them on this site. It's just a matter of snipping one wire underneath the ash tray (I think it might be yellow w/ green stripe). Simple mod.
