Turn Signal and High Beam Indicator light not working

Instrument indicator lights not working. Turn signals and high beams work, hazard switch works as well. I upgraded to a new flasher but prior to that the lights were not working. It appears both just stopped working. Not sure if it is bulbs but it seems odd that both would be bad.

 

Any ideas?

What flasher are you using?

The electronic flasher EL-13 from NAPA is the one to use for regular 21W incandescent turn signal bulbs* (all 4 bulbs should be identical). 

Connect the flasher as follows:

X to the Green/violet wire (+12v)

P to the Black/white wire (instrument panel indicator lamp)

L to the Green/yellow (4 turn signal bulbs)

The stock brown wire on the 4-pin plug is not used.

* Use the NAPA EL-13A1 if you have LED turn signal bulbs

Start with bulbs anyway.

In the original flasher relay, the repeater bulb in the instrument cluster is activated by a separate set of points inside the relay; it's not uncommon for that set of points to misbehave and not close, thus keeping the bulb from flashing.  So if you replaced the original flasher relay with another electromechanical one (not a solid state relay per John's post above) then I'd suspect the flasher relay.  They've been known not to work properly out of the box.  If that's the case, PM me for a writeup on how to tweak the oem style flasher relay so both exterior and interior bulbs flash properly.

 

As for the high beam indicator:  in daylight it's really dim, so check at night to see if it is indeed not working.  And if it's not the bulb, I'd check the high/low beam selector stalk on the steering column.  The high beam indicator lamp's wiring runs through that switch, and if there's a loose wire or dirt on the contacts, it won't work.
