Hello all,
I thought I'd chime in on this since I've been going through the painstaking process of sourcing replacement bulbs for my '01 Forester S.
I'd attempted buying 4 red 194s to replace the illumination bulbs back there after a short preliminary search of the forums, only to find out that they didn't work - they were too big! It would seem that Subaru changed the bulbs used for cluster illumination between years. I know for sure that it's not a 194/168/158, as all those are T10 (10mm) wedge-base bulbs. 194s are also too powerful at 5 watts output.
What I do know, for 2001 at least, is that it's listed in the service manual as a 14V 3W bulb. But no bulb type is listed. So began the search....
After checking all the usual places - Crappy Tire, PartSource, NAPA, etc. - to no avail, I called the dealership parts counter to try and get some info on the elusive bulb. As expected, he gave me the part number (85066GA390), the ridiculous price, and the fact it wasn't stocked. But then after a few mildly prodding questions, he revealed to me that it was a T5 wedge-base bulb. This was something I had suspected as the bulb's base was identical to that of a #74 - also a T5 wedge - which I'd noticed after pulling apart my cluster when I tried the 194s, and compared the two. A couple problems though... #74 bulbs have much less wattage (1.4w to be exact), and their rated lifetime is somewhere around 500 hrs, mainly because they're meant to be used as indicators (low duty cycle), not full-time illumination. Not to mention they aren't the same shape. #74s are straight from base to tip, and the 4 main illumination bulbs' globe part bulges out like a typical light bulb.
So.... after extensively trawling the interwebz for a couple nights, and after considering switching to LEDs a couple times and then deciding against it (as much as I love LED lighting, I have my reasons in this case) I came across one particular bulb on Mouser's catalog:
'JKL Components' EWG103.
14v? Check!
3 Watts? Check!
T5 wedge base? CHECK!
Downloaded the CAD drawing for the bulb, checked all of the vital measurements. Everything checks out. Even the picture on the product page looks identical to the bulbs in my cluster.
While the expected lifetime is a tad short at 1500 hrs (which, btw, is how long it takes 62% of tested bulbs to fail), if that means replacing them every 6 months to a year... at 62.6 cents a pop, I really don't mind at all.
I ordered 50. That's right, FIFTY. They're en-route, set to arrive on Monday. Will report back how they work out. I plan on either painting them red with Testors stained glass paint and/or using silicone bulb boots/condoms that are also on order from autolumination (6mm size, at .29 each).
In a somewhat related note, I also found some red 12V grain-of-wheat lamps (aka Microlamps) on eBay. Qty 50 for $9.99 + $2.99 US shipping from China. The seller was willing to ship a mix of red and clear as per my requirements, and I've also ordered 50 red 3mm silicone boots/condoms for those as well (from the same seller - wehonest_cn), to do all my switches and HVAC in red as well.
Pics will follow when all complete!
Hope the above can be helpful to others
