what are the bottom 2 lights for on my 84?

fiyaweed06 · 07-20-2009, 10:57 PM

I thought they were for the bright lights

3r!c84 · 07-20-2009, 10:58 PM

thats what i was thinking but i got high/low on the uppers

79gmcc15 · 07-20-2009, 10:59 PM

fog lights?

flamingbig10 · 07-20-2009, 11:08 PM

when the high beams are engaged the top and bottom lights are supposed to come on, are the bottoms lights even wired up

3r!c84 · 07-20-2009, 11:18 PM

yes there are i dont know where the bottoms wires run too?
but my high and low beam are done by the top lights

3r!c84 · 07-20-2009, 11:24 PM

i just went outside and looked and its all wired up looks stock.

72 CustomCamper · 07-20-2009, 11:18 PM

Low beam = top lights
High beams = all 4 lights

texasfunk · 07-20-2009, 11:41 PM

they might be burned out?

3r!c84 · 07-20-2009, 11:47 PM

yea then why would my tops work as high and low

it seems to have been said a few times, and i hope i dont seem like an ass, but when u have your lows on, just the top two work, when you have highs on all four turn on, meaning when you switch to high beams your tops can still be on even if the bottoms are burned out

3r!c84 · 07-21-2009, 12:00 AM

thanks but i get that.
what is happing is...my top lights are acting like both high and low beam.so when i turn my highs on the top lights get brighter and the beam of light moves up

i know how it should, but this is what i got

72 CustomCamper · 07-21-2009, 12:05 AM

The top lights are doing exactly what they are made to do...

3r!c84 · 07-21-2009, 12:08 AM

oh.
so the top should work as high/low and the bottoms should come on only when the highs are on?

72 CustomCamper · 07-21-2009, 12:12 AM

Yup

3r!c84 · 07-21-2009, 12:21 AM

thank you
Ill check them out tomorrow see whats wrong with them

**nlped** · 07-21-2009, 12:57 AM

Yeah, the upper light fixture has 2 elements in it...1 for low beam and 1 for high beam. The fixture has 3 electrical posts on it where the high beam fixture will only have 2 electrical posts because it only has 1 light element in it. On high beam the secondary filament in the upper fixture illuminates as does the single filament in the lower fixture.

Sounds like you have just got 2 burned out lower fixtures. I would get a test light and check power at the lower light plug before buying new lights though, as they probably won't be returnable if the light isn't the issue.

Good luck!

blaserman · 07-21-2009, 01:13 AM

My 84 Blazer did the same thing. I found out the bottom ones were burnt out. They are made to have all 4 on for high beams.

3r!c84 · 07-21-2009, 01:24 AM

yea im going to get the good ol volt meter out and see if i got power going to them.

and you say the lights are returnable ?

Ummm...negative, as they are an electrical item, most parts stores won't take a return of them.

3r!c84 · 07-21-2009, 09:14 PM

yea i got no Continuity on the lights.how many volts should be going to the light? i got 10.5 ish.with the motor off.
and a full battery

flamingbig10 · 07-21-2009, 11:12 PM

3r!c84 · 07-21-2009, 11:42 PM
