Combined Parking Light and Turn Signal, 1st generation Toyota 4Runner

This video contains flashing lights, if that bothers you, be warned!
Since the front turn signal stopped working, let's take a look at this modification while I get it going again.
On the 1st generation Toyota 4Runner and Hilux Pickup models, the factory setup was to have separate turn signal and parking lights. The turn signals were recessed into the factory front bumper and only visible from the front.
This modification fits a dual filament, 1157 type bulb into the parking light housing and eliminates the original turn signals. This is the same type of bulb in the rear tail light housing for the brake and running lights.

This page also has links to alternate modifications using different types of bulbs. I made this modification in the late 1990s. Aside from one broken housing that I had to replace, this has been working great since then.
In short, you take the 2 wires that ran to the turn signal and the 2 wires that ran to the parking/running light. Of those 4 wires, 2 are ground connections, use one or both of those wires to connect to the common/base of the bulb socket. Then connect the remaining parking light wire and connect to the low wattage filament terminal on the socket and connect the remaining turn signal wire to the high wattage filament connection. If you find the turn signal is dimmer than the parking light, just swap those two wires.

I going to try this mod this weekend. Thank you.

It's worked well for me for many years. Not sure why Toyota ever went with the separate lights in the first place.

Great idea, its been while since you put out this video. Can you please which wires you spliced to make it a turn signal? Thanks so much. Great videos.

[@The4Crawler]

See the video description for details. In short, the wires to the original turn signal socket have ground and the turn signal connection. Likewise the wires to the original parking light socket have ground and the parking light connection. Just combine the 2 grounds and then connect the remaining wires to the turn signal (bright) and parking light (dim) terminals on the bulb socket.

Ahhhh!!! Thank you so much. Makes sense now. I can install my smittybilt bumper now.

@@allanagustin8760 I had a SmittyBilt front bumper as well and never liked the way they mounted the turn signal housings between the 2 tubes. In the winter, that area would pack with wet snow and you couldn't see the turn signals. Also, vehicles to the side could not see the signals either.

This isn't related but I found your website online, and I'm fixing up my 87 Toyota 4runner , but I'm having a small problem when I turn my head lights on it seems to lower the rpms like a draw . I replaced the alt. Not sure if it's a concern but the ecu relay gets hot to the touch and the taillight relay does as well. Not sure if you had this issue and could offer a little insight

@@rustyviramontes1260 Hard to say. If you have a clamp on DC current meter, you could try testing current draw on the various circuits and see if there might be something on one of them drawing too much current. On the relays, you can pull them out and then insert meter probes into the load contacts, usually the 30 and 87 terminals, and measure the current that way, might work for the tail light relay. Perhaps something has been tapped into that circuit and is causing a problem, like an alarm system or towing light adapter, etc.
It's somewhat normal for the engine to slow down at idle when a load is put on it. That's why there's idle-up valves on the power steering pump and on the A/C system, if present. Those idle up systems bump up the idle speed when those components are used. Unfortunately, nothing for the alternator.
You might try this thread search on Yotatech and see if anyone had a similar issue:
