Steddy58:Your signature line says that you have a 1988 Savage.
According to the wiring diagram for 1987 through 1994 LS650's, you
should already have just one single indicator light for the turn signals.
If yours has two separate indicator lights it may be because the wiring
diagram is wrong or that it doesn't apply to UK versions of the Savage.
In either case, you can convert to a single indicator light by connecting
it as shown in this diagram in the Technical Section:
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1294779818You don't need any diodes or relays for this.
Just connect the two wires from your single indicator bulb to the green and
black wires that go to the turn signal switch.
I think you can splice in to them in the headlight enclosure.
Their colors won't be green and black at that location but you can find the
correct wires with a test light.
Two things to consider:
1) You must use a standard low wattage, incandescent indicator bulb; not an LED bulb.
That's because it must be able to conduct +/- voltage in both directions.
2) The turn signal bulbs must be standard incandescents, not aftermarket LED's.
That's because the small indicator light uses the heavy filaments in the
turn signal bulbs to complete its ground (-) connection in both directions.
Use the standard bulb numbers: 1157 Front, 1156 Rear
By the way ... the wiring diagram referenced above has at least one error that
I've found. It shows both of the front turn signals connected to the left turn circuit.
You can still use the diagram for a reference on how to connect your single indicator
bulb, but it will confuse you if you try to trace the wiring beyond that.
