Headlight Globe Power Rating

[oldcorollas]

KE10's do, but i thought KE30 rolla on had headlight relays?

fwiw, legal size is 55/60, anythign higher is not legal...

I found the Narva Plus 50's quite good, nowhere near the 130/90's I had but better than the "white" 100/90's I'm currently using in one car.

Are you sure?
Every Toyota I've had has had a 'HEAD' relay in the engine bay fuse box.
It would be common to run all the tail lights off the stalk, but not the headlights.

Ahh, yes, there is a relay for the headlights, but it doesnt do what you think...
Main power for the headlights still does run all the way back to the stalk.

An example:


Measure the voltage across the actual headlight globe when its on, and youll find its a decent amount lower than the battery voltage.
Youll also find that a globe thats 10% down on voltage might be 40% down on brightness.

I installed a Bosch headlight boost kit on my Starlet and then my GT4.
Its basically a couple of relays and new thick wire (factory wire was about 1/4 the size) to replace the factory system.
It made a big difference in headlight brightness.

I may just run a relay for the high beam and relay for the low beam and give
them direct battery voltage since my lights are poo. Also what other cars
have the same reflector as the ae86?

[oldcorollas]

can you get Hella inserts? they tend to have good reflectors and lenses

sorry to revive thread but would you happen to no if the ae86 levins headlights would be able to handle 100/90w globes? I've upgraded my harness and trying to avoid melting my reflectors. Oem is 60/55w

I ran 100/90w globes in my AE86 Japanese Levin spec housings for years without an issue. Was always a little nervous about it though. When the loom came out later, there was no evidence of heat damage. Also always ran uprated 80 / 100w inserts in my TA22 and various Datsun 1600's prior to that.

Subsequently I bought a GTV underdash and accessory loom and found that it had evidence of heat damage at the globe plugs and also the lights junction box under the dash. I presume this had come about from running higher than standard wattage globes.

In future I will be running a separate relayed power supply. Simple enough to do, and cheap insurance.

I wonder with the move to lower wattage / cooler running globes in buildings, when will this technology hit automotive applications, or has it already?

Hi,

There was a 100W driving light option, for the inside globes, for the 70-77 Celicas. I was under the impression the wiring was capable of handling this power. But, these cars being old now, I think it's best to upgrade your wiring to the headlights if you are going to vastly increase their wattage.

However, unless you are doing a lot of night driving in the country, where 100W spotlights would be the best option, I can't see the need for anything more powerful than the usual 50-60W globes.

I think they are a standard 7x6 headlight, look at stuff like Hilux etc or buy Hella units new. More common to find the semi sealed housings on commercial stuff at the wreckers, there are also various fancy aftermarket lenses that will fit.

On the trueno you can, havent seen them for the levin/adm headlights.

[WDE_BDY]

Oh yes, you are correct. Best thing you can probably do then is clean the inside of the housings, upgrade wiring with relays for high and low beam and run the plus 50 or plus 60 bulbs.
