im sorry but this prob has been ask an 100 times already...but i just wanted to know if i can upgrade my hid to an blue and brighter hid on my GS ???

 

Yes........

 

Yes you can!

Get a pair of aftermaket D4S bulbs.


Check out Mobilehid.com they one of CL approved vendors.

 

arent a majority of lexus' d2r reflector designs?

the older ones yes, most now are D4S w/ projectors

 

someone.. please please teach him where the search button is

 

was that to me? lol. sorry i dont own a newer car, and do all this crazy research about everything that i dont own.

6k and 8k temperature bulbs may look nicer, but light output is lost. i know that a standard d2r bulb 85126, but are offered as 85126+. they may do something for the d4s bulbs as well.

You get get bluer, but it wont be brighter, in fact it will be dimmer. The only way to go bluer and brighter is to upgrade to higher wattage HID.

 

lol, definitely not to you, if you see the trend of some of OP's post, you'll see he is posting about some of the most asked questions. I don't mind helping them once a while, but when i have to post the same thing over and over again, it gets really frustrating that I even bother searching for my old post and copy and paste the exact same thing when they could've found it themselves.

D4S is the same, offered in 6000k and higher, brighter, mercury free and less voltage needed.

sucks that Philips stopped making the 5800k XenEco bulbs for D4S

 

yup but not recommended unless you also upgrade the harness to handle the higher power, plus it'll run much hotter, not too good for stock housing too.

Personally, i think the best compromise for going to 6000k+ is to have HID fogs to get some of that lost "lumen" back.

 

Agreed with whlkev.... ive said it in his threads before... use the search! is it that hard?

 

Yyyyyyyep!

 

The higher the Kelvin (K) rating doesn't mean it's better, OEM is 4,200-4,300K. That gives the best light output. Anything higher degrades the brightness and visibility of the beam pattern especially in inclement weather. Changing out the wiring harnesses has nothing to do with light output or imprmoved brightness. The bluer/purple the light is, the less effective it is in lighting up the road in front of you.

 

^^

we were talking about changing the HIDS to 55W version hence the need for beefier harness

everything else you've mentioned, you are of course dead on like always

 

Do you even need to change wire harness with the 55W HID? What is the start up amperage of the 55 Watt system?
