View Full Version : Are 80's 4runner lights compatible with MK1 mr2? Looking for more light


traintech8601-08-2013, 12:44 AMI have a 87 4Runner and i am looking to upgrade the lights. I did some reading and i found these:

Rectangular Toyota® Conversion Headlamps - Toyota Headlamps by Roundeyes™ Inc. (http://www.roundeyes.com/Toyota_Headlamps-Rectangular_Toyota_Conversion_Headlamps.html)

I then remembered that the MR2 lights look very close so i went to philips sight and they have the same lights listed for both. I did some reading and all i can find on these boards seems to be 6$ ebay kits. I know most AW11 guys are cheap skates but i wanted to know what you guys think about these lights? i am ok with the price but if there are better deals that don't sacrifice quality, i am all ears. The 4runner forums are nowhere near as active so i hope i get some answers here. I'd like to add i plan to by a set for the runner and a set for the MR2. Prometheusecks01-08-2013, 08:52 AMAs far as lighting upgrades go for the MR2 I ended up purchasing these from twosrus and love them:

200mm Vision Plus DOT Headlamp, Twos R Us (http://twosrus.com/catalog/product_info.php?products_id=731)

Throws a lot more light down the road and as an added bonus has a replaceable H4 bulb. Also is a direct replacement for 6012, 6014, 6015, 6016, 6017, H6024, H6014, H6017and H6026 Sealed beams.

Not sure what the 4Runner uses but if it is any of those it "should" fit. w1jim01-08-2013, 10:38 AMThese are standard 200mm rectangular headlights.
Search out some Hella replacements or for less coin get the Autopal headlights (http://rimiusa.com/index.php?main_page=index&cPath=7). traintech8601-08-2013, 12:27 PMSo i looked up the hell lights and i thought of something. Will these be pulling more juice? I don't wanna fry my car and or truck up with its old ass wiring. Thanks for the input guys!

Hella 200mm Rectangular Headlamp Replacement w/ High Wattage Mega White Bulb (http://classicgarage.com/he-72206bw80.html) w1jim01-08-2013, 12:49 PMYes - if you go with the high wattage bulbs you will be drawing more power and could toast your headlight relays (or if not so equipped, your headlight switch). Your best bet with these particular bulbs would be to install relays that get their primary power (through a fuse) directly from your battery.
Or specify the standard 55 watt H4 bulbs and it will be plug and play. Iroke01-08-2013, 04:29 PMtrain!!! lol our headlights are the same for anything that uses a 7x6 headlight most 80s toyotas and other company use them too
just run open backs with hids
i picked up an 85 2 weeks ago! traintech8601-08-2013, 09:40 PMiroke, long time no see buddy. 85 what? and i think i'll order them, and the 55watt bulbs since that shouldn't be a huge drain. i don't know to much about the relays... I will have to see how the lights on my 2 are. i only considered the upgrade cause my 4runner has horrible horrible bulbs haha. they aren't bright, they aren't straight... i try not to drive at night till i can aim them haha Iroke01-08-2013, 11:54 PM85 4runner
5 inch sky jacker leafs 35" tires and solid axle gona swap my body over along with the 7m install

What do you mean by this?
The voltage regulator insures that the alternator voltage doesn't exceed ~13.8 volts regardless of engine speed. It doesn't effect current draw (amps) which is the issue with more powerful bulbs. Normk01-09-2013, 11:50 AMA fairly reliable means of determining whether then headlight load is acceptable, is to voltage drop test the component (such as relay) or circuit in question. Anything 0.2 volts or greater is a rule of thumb value indicating a problem.

The ND alternaotr used on the MR's is a typical automotive, internal regulator one. Alternators are considered to be self limiting with regards current output so do not require a control to limit current flow. A 50 amp alternator will deliver a maximum of 50 amps (plus a bit in the case of the ND), change it out for a 70 amp unit and no difference will be noted unless the electrical load exceeds 50 amps.

In operation, with sufficient engine RPM, the voltage regulator controls (limits) alternator rotor (field) current to maintain the voltage set point designed into the regulator. This voltage set point is usually in the 14.2 to 14.6 range for alternators of this vintage. If electrical load is added (such as switching on headlights) causes system voltage to drop. This drop in voltage will cause the voltage regulator to react by increasing field current sufficiently that the system voltage increases to the set point. Turn off the headlights, voltage begins to rise above set point and the regulator reacts by reducing rotor field current to reduce alternator output to match load such that system voltage stays at the set point.

I repair these alternators for several motorcycle applications, have repaired hundreds of alternators in the course of my professional automotive career, and so am reasonably familiar with their operation.

Someone will likely observe that there is little need for this kind of service today because parts and labor costs shift the economics to new or factory sourcing. One has to have some industry knowledge to even find replacement parts in most areas.

HIH w1jim01-09-2013, 12:03 PMMy main concern with high current draw headlights is that the stock switches and relays are not designed to handle twice the current these draw. Upgrading with a larger relay(s) and heavier wiring is in order.
Several years ago I was doing course closing (tracker) duties at the Susquehannock Trail Pro Rally (in PA) when my headlight switch got toasted.
Not fun when you have to rely on the fog lights and pulling the stalk back to the high beam flash position for lighting, especially in the corners. Iroke01-09-2013, 04:41 PMi ment what normk said
thanks for explaining so i dont have to traintech8601-10-2013, 01:37 AMnice iroke! i really wanted a 84-86 solid axle stick I4 but i managed to come up with a cheap I4 Auto 87... that being said, i think 218 k is taking its toll as i don't think the trans is putting down the power to the wheels. my father corrected the timing but it just feels the same as when my mr2's clutch slips. it sounds like the same symptom is possible with an auto. saddly i didn't get my mr2 back but ill post about this in my other thread. glad to see you got back in the 80's toyota business!
