can y use this bulb in my 99 rx300 ? without change noting? (not use harness)
i have a fear about the wires. I' ve check and the fuse support the current, but what about the wires?
i bought it in a impulse. Does someone has a real experience with ?
thanks

hypervish

Did you buy ballasts with it?

100W is too much.

edupim

no, in the ad they say it is not necessary.

hypervish

If in fact you did purchase an HID bulb like your title suggests, then there must be a ballast in order to light the bulb. No way around it.

Either way 100 watts is too much, the stock high beam bulb is 60W.

Xenon Gas and Xenon HID are two different things, which one did you buy?

edupim

this is the bulb i bought.

that is my fear, if i will over charge the wires

kalali

At $5.25 a pair with free shipping I'd go with gas...It also says high beam so it may not even fit the RX.

hypervish

That is in fact a Xenon Gas bulb like Kalali mentioned. It is plug and play, for the high beam (9005, low beam is 9006). However, as I said numerous times before 100W is too much.

I suggest you return it.

Lexusblack

it should come with a kit, which includes bulb, ballast and wires. If they didn't send it to you, you should return it.

mizak82

would those things even work?? i paid 50 a pair for sylvania ZXE.. They are awesome.. but for 6 bucks maybe I got ripped..

edupim

hi hipervish. thanks your post.
could you technically explain the reason that i have to return?
100w /13.8 = 7 A if you inspect the diagram you can see that the fuse support 15 A.
i m open to hear any comment best if it is technical

kalali

Amps is one side of the coin. The other side is heat.

hypervish

+1, the 100W bulbs generate too much heat. Could possibly melt the plastic housing. Also, the wiring harness can not handle that.

If that isn't reason enough, then I don't know what to tell you. Run them, but if something goes south, I'll be the first one to say, "I told you so"!

Fuses are selected based on safety - max current carrying capability of a branch. The normal current in the branch is typically a fraction of the rated fuse.


If you measure the resistance of the bulb and apply Ohms law, you will find the current will be lot higher than what you calculated. And when you switch the bulb on, the current is high ... till the filament heats up and then you draw the rated current.

Folks generally have incorrectly associated lumins to watts. If efficiency is the same then it would be valid association.

Here are the reasons not to exceed rated watts (by all means go for higher efficiency bulbs as they will draw less current or produce more light for the same current)

All things in the circuit (switches, fuses, wires, connectors) may not be able to sustain current demand.
Higher wattage bulbs will produce more heat and the socket-connector- wire-insulation will get charred.

Those bulbs will most likely melt your headlights. And melted headlights are not fun. I bought something similar and they destroyed the inside of the clear fog lens. The fogs are useless now even though I put the stocks back in.

edupim

ok people. by love to debate.
i know that fuse are projected to 30% more that the normal current
I will to measure the cross section of wire to calculate the current that sustain.
I will check out the the bulb resistance and i will measure the true current (light on)
i know too that they write 100 w but i'm not sure that is real. For me it is a way to give a wrong impression that the result lumens will be good.
the example about the internal space of fog light is reduced and in this case the heat inside do not have way to dissipate.
the time that the current is over (starting time) is very short ( in resistive charge) like inductive charge the current of start of motors have a pick
About the connector, normally the poles do not fit well and them in this point will increase locally the resistance, normally the contact surface have to have twice transversal section (minimum) of wire.
any way, first thank you for the words and the time. i will make the measurements
and post in this forum. Please, don't get me bad I don't want be stubborn, just want to go deeply
